I stayed in this private room for 4 nights in July 2019.
Carlos is very friendly and welcoming, and offers his advice on places to visit, interesting restaurants etc.
However, the room was quite disappointing. My friend and I had bunk beds, the room is extremely small and not very comfortable (the pictures give a completely different feeling). To put it in perspective, I would compare this room to a closet with two beds and a window.
The apartment and bathroom are very clean.
During our stay there was construction work in the building, so we often woke up with the sounds of the work in the morning.
Public transport (bus or metro) is not really close to the apartment
