Rosa's apartment is great. Very clean, with a good kitchen area, which is well-stocked with utensils and pots and pans, and a nice bathroom. The room is also clean, and you may need a fan in the summer (they have fans there). The bed is comfy, and sheets are changed every Friday, along with towels.
There are 3 other Airbnb rooms there, but you have a lot of privacy, if you want it. The washing machine and dryer work very well and the lounge area is lovely to sit in.
The area is perfect - very central and well connected by metro to more touristy places.
