Perfect location, very close to Sao Bento station. We regularly found ourselves near the apartment and would stop in for a quick refresh to use the bathroom, then easily continue on with our day's activities. The garden is a lovely, quiet spot for a glass of wine and I even enjoyed some morning yoga in the lawn.
The only downsides were that you could hear any hallway noise as people enter and exit the building, as well as the neighbors walking in the apartment above. Considering the proximity to the noisy R. da Flores, we found the apartment relatively quiet and this wasn't a problem for us. The other thing I will mention is the bed was very stiff and not the best for side sleepers.
Overall, this was the perfect spot to stay and Modesto was extremely communicative and welcoming!
