We had a good experience in this apartment.
Ruben welcomed us at our arrival, he is very sympathic.
The apartment is clean, spacious and the view is superb.
The localization is centrale, at the door of bairro alto but very calm. We did a lot of things walking, but public transports are not far, about 10min walking.
We traveled with a baby of 7 months, so the 4th floor was not easy but possible. A baby bed was disponible in the apartment.
The only negative point is that there are works in progress in front, with a construction crane, so it was difficult to enjoy the terrace, but not very noisy with closed windows.
