Nice apartment, great location and a helpful and flexible host.
Both the downtown and the Ribeira can be reached comfortably by walking. The building where the flat is situated is not so beautiful, but otherwise we didn't have any problem with it, it was really calm and quiet. The apartment itself is nicely renovated. The living room is a common space with the hall, kitchen and dining room, and I would say that it is a bit small. Also, don't expect to cook a lot in the kitchen (although it is possible). The bedrooms are spacious, and the beds are quite comfortable.
All in all, we really enjoyed our stay at the place of Daniel and Nuno.
