I was very pleasantly surprised by the facilities (probably because the description makes a point to highlight that it "isn't a 5-star hotel," and describes it as hostel-like). The common space/kitchen was large. The whole place was clean, well-upkept, and not crowded. I didn't have to wait once to use a shower or toilet. The location is great -- very close to many food places, markets, and locations for entertainment. It's also just a short walk to bus and metro stops.
The room was great -- plenty of space, high ceilings, good temperature at night. The king bed is made up of two half-size mattresses inside a king frame, but we didn't notice anything uncomfortable while sleeping.
Check-in is very easy -- Alex sent us a very detailed message with great directions and instructions. The door code made it flexible for us to check in at any time. The room is up a couple flights of stairs but there's an elevator.
It would have been a 5-star stay if not for a check-in problem. Someone took our room, so we had to stay in a different (much smaller) room for one night, and then the next day the party that took our room didn't move out until late evening. However, during the whole problem, Alex was helpful and proactive, and fast at communication. We got a partial refund for our first night.
