My stay was great! The entire building was spotless and looked exactly like the photos. The garden was a nice little refuge on a hot summer day. Alex and Lina were great - they were not only helpful, but just really nice people. The pets were also good fun to have around, and make you feel at home.
I felt completely safe in the area, and found it to be well-located. There's a Subte stop a short walk from the apartment.
I wouldn't hesitate to return, or to recommend the room to other travellers. It is on a bit of a busy street, but it is in a major city, so I feel like that's kind of expected .
