This room was quite good. It looked exactly like on photos, and I want to highlight that all house even toilets are REALLY clean! I was met by Mariana's mother and we managed to understand each other although she doesn't speak English.
But there are 2 big BUTs:
First of all, noises. Doors slamming (which is impossible to avoid), loud talks in the corridor and next rooms - it was impossible to sleep. There are 8 bedrooms at this apartment so if you are light-sleeper like I am, you might suffer. Looks like there is no any soundproofing, I slept with ear plugs, but it didn't help much.
And secondly, it was cold. I was freezing, so I slept fully clothed.
These two nuances made my stay not really good. But that was only my experience, which is not relevant to everyone.
