Ari seemed a nice guy, he was very responsive in our comms, not much English but that was not a problem for me. The room was more spacious than expected and the location was great, literally right next to the Selaron stairs. There are some things I want to flag though: given the vicinity to the stairs, you could hear noise till 3/4am. Also the bed frame was unfortunately VERY squeaky. On top of this, while the room itself was in passable shape, the rest of the apartment was a bit dirty. The kitchen was left very messy, and the apartment was littered with dead wasps/bees/bugs(?). I only stayed a night and am not usually fussed by these sort of things so it wasn't a huge problem for me, but am flagging this in case you are. All in all, this is a good place for a brief stay in the centre of Rio if what you need is a place to sleep after spending the whole day out and about.
