This apartment is an exceptional place for your stay in Lisbon and I recommend it without reservation for both the location and the layout. We were two couples staying for a week, and with the two bedrooms, each with its own bathroom, one upstairs as a loft and the other downstairs, it worked out perfectly. And you could hardly find a more convenient place to stay! We could walk downtown, to the train station for daytrips, along the beautiful Avenida, to Alfama and Chiado for sightseeing and some amazing restaurants (there are also some right nearby that Mariana listed in her very helpful folder of local information). We thought about some apartments in Chiado and Baixa, which are centrally located, but decided on the quieter neighborhood and boy were we glad we did. Once we got there, we discovered how noisy those areas are. Also, it's hard to understand in advance how very hilly Lisbon is, and how narrow most of the streets are. This apartment is on a typical narrow, hilly street, and it's on the third floor, so be prepared for some climbing. There is a good supermarket nearby as well.
Mariana was very responsive and resolved any minor snags easily. The apartment looks brand new, with stylish furnishings and a convenient kitchen. The linens, by the way, are luxurious in quality -- a definite highlight -- and the shower was strong, unlike many in Europe. Lisbon is a truly amazing city, and this apartment is a great location from which to explore it.
