OnJ S. Lázaro Lisboa

We’ve just returned from a five-night stay. There were three of us, and we stayed in a two-bedroom apartment, which was lovely and very modern. My daughter celebrated her birthday during our stay, and the staff surprised her by bringing a cake to the room, which was a really thoughtful touch. The location is great — just a five-minute walk to the centre.

This is a lovely hotel and convenient location. Very friendly helpful staff. Everything is good except sound proof in the celling. Every day around 7am during our stay, we're woken up by at least one "elephant" above our apartment, the "elephant" (or "elephants") above apartment was either walking heavily, running sometimes and jumping. I briefly expressed this with the staff and she only apologised. This is the one downside to our stay. Apart from that I would have given it 5 stars.

Great hotel. Staff is very friendly and really takes the time to make sure you are comfortable and have everything you need. We were there on a city trip, when we arrived the receptionist straight away offered some drinks and sat down with us to go over the map and give recommendations. Really appreciated! Rooms themselves were comfortable and clean. And the breakfast was the best!

Beautiful Boutique Hotel with the friendliest staff. Had a (too) short but excellent stay! Can recommend the brunch at the restaurant too. Will come back for sure. Ps: pic shows the little shop across the street

We stayed at several hotels throughout Portugal and had excellent experiences everywhere except here. Unfortunately, a number of issues affected our stay. When we arrived, the sink was already clogged. Although we reported it immediately, it was not repaired until our fifth day. The shower temperature also fluctuated whenever other sinks in the building were used. Throughout the stay, we found multiple spiders in the room. Midway through the trip, the heat turned on automatically and we had no way to adjust or turn it off, leaving the room uncomfortably warm. The dishwasher also failed to work properly, and after using it we were told that leaving dishes on the counter created extra work for housekeeping—despite the fact that the dishwasher itself was malfunctioning. We were also met with inaccurate accusations, including being blamed for a clogged toilet despite it clearly being a plumbing issue. Although the hotel had a “priority housekeeping” feature, it was not honored; housekeeping consistently arrived around 4–5 p.m., and on the sixth day they did not come at all. Additionally, the ceilings are not soundproof, and we experienced constant noise from upstairs throughout the day. Booking an extra night was also difficult—we tried repeatedly to contact the hotel despite availability, but it was nearly impossible to reach anyone. Finally, on our last day, there was no warm water for showers. Overall, this was the only disappointing stay during our time in Portugal, and we hope the hotel addresses these issues for future guests.

I had a great stay at the OnJ! My room was spacious with open windows to take in all the sights of Lisbon. The beds were also comfortable, which was a huge plus. It’s only A 10/15 minute walk to downtown with tons of restaurants and shopping. The staff were amazing and extremely welcoming! I’ll be returning on my next trip!

I briefly considered whether I should even write a review. Not because the stay was bad, but because I fear that if too many people find out about this hotel, it will soon become overpriced and overcrowded, like all the other hotels in Lisbon. I had a wonderful stay at this hotel. Everything is just right: a great concept, spacious rooms, reasonable prices, and super friendly hosts. The hotel is within walking distance of the city center. Some guests complain about the lack of security in the neighborhood and even though I agree that Martim Moniz isn't the prettiest place in Lisbon, even as a solo female traveler, I had no problems.

We were overwhelmed by the kindness, hospitality, and how beautiful the hotel was. They were so thoughtful about everything and made sure we had everything we needed. Stunning building and gorgeous rooms. I would book here again in a heartbeat!
