The house and the room are very lovely. Staying there felt like being home. The location is excellent, you can get everywhere very quickly and many things are in walking distance.
Only negative point: Getting to the bathroom from the top where the room is located, can become a bit of a mission, since you have to climb stairs which are located outside. Not very comfy in wintertime and when it rains. However, the gorgeous room and the view, will compensate for that. If I ever go back to Buenos Aires, I want to return to Maria's house.
