Fali was very accommodating with the times I was able to check in, and the room was just like the photos. It's a nice large building, with many floors (this room is on the third floor, I think) and there's not a lift, so if you have a problem with many stairs, probably choose somewhere else. Otherwise, you get fit, which is good.
There are many rooms in the building so there were usually different people about, but that wasn't a problem, and the lounge/dining area is large and there is plenty of room to move.
The only thing that concerned me was the neighbourhood. While the building is close to La Plaza De La Merced, it's necessary to go down another street to get there. In the evening, that street was either empty of had groups of men hanging around.
People may say it's a safe neighbourhood and nothing would happen, but all I can is that along that street I didn't feel safe. I was a single female walking home late at night, but if that's not your situation, then you'd probably feel fine.
It's definitely an interesting place to stay in, and Fali is fantastic, so give it a try!
