The room belongs to a flat with (if I'm not mistaken) 7 more rooms, 3 bathrooms, a big kitchen, a small hallway with view over the city and a nice living room.
The flat is used as an hostel, I did not physically meet Mariana or Fernandes, which is per se non necessarily a bad thing, just so you know what to expect, there's not much personal contact with the "owner". It wasn't needed either, we could very easily get the keys and enter the apartment and the room, thanks to the clear explanations in the welcome message.
Bathrooms were cleaned daily, furniture looks from Ikea (so essential but functional), but they added some nice decorations around the flat which makes it way less impersonal - I particularly liked the hand writing straight on the mirrors and the walls, infos and tips ;-)
The room was quite small, but we knew that from the description.
Location is incredible, you're in the heart of the city center, too bad the city center is all hilly, but you can't blame them for it :-)
Also, there were some festival in one of the side streets over the weekend and we could hear it at night, but again, you can't blame them for it :-)
All in all, I would definitely go back, probably taking a bigger room if they have it!
