ONE°15 Marina Sentosa Cove Singapore

I am sorry to write this review and I really wanted to like this place but I just could not. I paid 5 star price for a 3 star quality hotel. No bell boy when we arrived at the hotel after 10pm. We had to drag our massive suitcases down, some stairs then onto elevator. The staff at reception were nice but NOT the 5 star service I was expecting. No proper welcome into their hotel like you expect to feel. The hotel/resort gave out no 5 star vibes. The breakfast was below average. I do have to mention that a young Indian ethnicity looking gentleman during breakfast may have been the only staff who had excellent service and communication but everyone else fell short from what I had expected. The rooms were of 3.5 star to 4 star quality. I was so disappointed only because I paid over 750AUD per night for an absolute below average hotel. Often when I called reception for waters, there was no answer. On our departure date I called multiple times to no avail and I was forced to walk down to lobby to request for bell boy. My apologies for this review once again but paying so much really left a dent on this experience.

I hesitated to post a public review because I strongly believe in giving customer service the opportunity to address my issues, and I understand that operational hiccups can happen. Unfortunately, my experience at Monte Carlo 2 Suite, was never properly addressed despite multiple follow-ups. After rainfall over the night, staff was outside the unit at around 7:30am to clean and dry the floor, which already disrupted any rest. Shortly after, between 8–9am, the suite beside seem to be hosting a wedding. Large numbers of people were constantly pacing the corridor and gathering outside the room, with loud conversations, celebrations, and noise throughout the morning. Rest was completely impossible. I was not told about the event that would be held in the morning, which would have encouraged me to change my plans in advance. Unfortunately, this made me feel that this 5* hotel prioritises event plannings over other guests. Additionally, the balcony was heavily infested with mosquitoes, making it unusable and preventing any enjoyment of the outdoor space. What was more disappointing was the lack of follow-up from customer service. After sharing my experience, I was told the matter would be escalated to the relevant department. I haven't received any follow-up despite expressing that I would appreciate a clear timeline for resolution. A timely response and proper resolution from management would have changed my perspective, especially after having my partner's birthday celebration disrupted by these issues.

I had our solemnization and lunch reception here at the Nova room and we are truly happy with the service and coordination. Love the location and ambience of the Nova room as well as the location. Additionally, the prompt response from Beck Chin is one of the important aspect we have decided on the location. Prior to contacting ONE°15 Marina, we have contacted several other hotels. However, most of the time, we were met with slow response, unlike Beck Chin, he has been very prompt in response right from the start of our enquiries till after the event. He has been a great help in coordinating our needs and gave good suggestions along the way. Perhaps, the room is slightly below our expectation. The lighting is pretty dim and relatively basic. The hefty deposit is rather uncommon as hotels would typically use credit card as guarantee. Additionally, the hotel should consider to provide flexibility for early check-ins for bridal make up as that would would certainly be helpful for couples having lunch reception. Again, thanks Beck Chin for the help to create a memorable event for us.

I had an incredible experience here in September 2025. The property is quiet, beautiful, and perfect for remote work. The location is fantastic, with stunning views of both the hillside and the marina. There are great dining options nearby for the evening, and the area feels safe and welcoming. The staff were friendly, helpful, and attentive, making the stay even more enjoyable. Highly recommend for anyone looking for a peaceful getaway or a great place to work remotely!

Recently held my wedding at ONE°15 Marina and me and the wife's experience was immaculate. My first contact was with Beck. From the start up till the very end, he was responsive and attentive to our needs. He would reply us almost immediately anytime of the day and would follow up with any of the unknowns and queries expeditiously. Beck is also knowledgeable and sensitive to cultural/religious norms; a major plus for our multicultural wedding affair! Thank you Beck, we had a good feeling after we first met you and we were definitely not wrong! On our big day, banquet manager Joyston was assigned to us. I had met him the day before for coordination and I must say I was impressed by his grasp on our wedding itinerary. He was able to remember specific details regarding the events! Along with the bridal team, groomsmen and vendors he was able to facilitate a smooth flow of events. Although it was a short engagement with Joyston, we are thankful that we had experienced the amazing service you provided. The backdrop of the yatches and boats along with the decor provided made for a beautiful venue. The rooms provided for us, though just slightly dated in certain aspects, were very clean and comfortable. Service provided by staff was timely and efficient. Thank you ONE°15 Marina for an extremely memorable wedding experience :)

It was our first time visiting One 15.. Apart from the amazing location, the hotel was situated pretty conveniently with Cold Storage, 711 & Little Farms, just a stone away. The bathtub could be better, as it is very sunken and deep, and it can be very inconvenient for elderly people or those with knee problems. We didn't go for the breakfast option as it was not halal certified, not many options, and not cost effective. The gym facility was not good as it is only open till 9pm for non-members. It is 24/7 only for members, which I find quite unreasonable as even non-members paid for the hotel. Our view was excellent, it was facing the marina and we loved it. Another part of concern was that anyone could enter the hotel from the back entrance and access the lift to go up to the rooms. The lift does not have any access card system. Anyone can just come in and access the floors, which can be quite alarming for security reasons. Other than that, all was good. Our operator managed our stay extension very smoothly and even allowed us to check out at 1pm. Thank you to all who made our stay pleasant.

We held our wedding here and we could not be happier! Beck Chin was a great coordinator throughout the months of preparation, extremely prompt at replying and very helpful Joyston was a godsend during the day of the wedding. He kept my wife and I calm and collected, gave us very clear instructions every step of the way and made sure we were well taken care of throughout Could not have had a smoother wedding, thank you to all the staff that helped out!

The place was amazing! The amenities too are top notch. The room was very big and bed comfortable. We are hoping though that the staff would be friendlier and that there would a bellhop to assist. Our luggages were too heavy, it would be very nice if there will be someone to assist us going up and down the stairs.
