Short review: Old-fashioned room with all your basic amenities on strategic location. By the time I was staying there, the pictures provided here are pretty accurate.
TLDR: I was staying there for 5 nights and, as a Bangkok newbie (first timer even) and solo traveler, I could say this is a GREAT location to stay in. Located close to Khao San road where many say the backpacker area, so expectedly there are tons of street food and/or local food stalls anywhere. If you aren't too keen about trying local food (which I am not and you shouldn't LOL), there are restaurants that serves Western food as well. Coffee, bars, and 🍀 go without saying. They are everywhere.
Some more pros:
+ Has laundry service that can be done within the same day
+ Great staffs with warm personality and helpful manner.
+ Room was basic with quite an old style room but has anything I need so I have nothing to complain about. When I checked in, everything was kept clean and tidy.
+ There are 2 ATMs right in front of guest house in case you need to draw cash ASAP.
+ Free Wi-Fi, but there was moment where I couldn't connect. Turned out they changed the password and happily informed the new password when I asked.
Next is not a complain, but worth mentioning especially for those with mobility issue. I stayed on the 5th floor and the only way to get there is stairs. Mind you I don't mind using the stairs, but after getting drained from strolling around Bangkok and partying (I was there for Songkran), elevator/lift would be very helpful. I think they have one but broken, maybe? I didn't ask though. So be mindful with your situation, condition, and plan.
Another "mobility" stuff I need to mention is there are no MRT/BTS nearby so your options are wheeled vehicles or your foot. However, you shouldn't worry much about it as there are tons of options. Tuktuk, taxi, or online driver (like Grab or Bolt) are available. Bus stop(s) also within walking distance. On top of that, there is a boat pier in one corner namely Phra Arthit that can take you to some iconic spots like Wat Arun and Icon Siam mall.
