The location is in a part of Lisbon where there are still a lot of locals. Small streets, little shops, but still only a short walk to Santos, Cais do Sodré, etc. Really liked the calmness of the site and the surroundings. But be aware: At about 23pm, the garbage men will provide some noise and might actually wake you up if your windows aren't closed.
The apartment is new and looks just like you can see on the pictures. The bed was comfy, the table provides sufficient place to also do some work. The basin is quite small (you'll have a rather hard time to shave, guys), but the shower is of top quality. The kitchen is quite small. It won't be easy for you to find a place for everything after some big food purchases. When I arrived, a few tools were still missing in the cooking arsenal, but Joao was always eager to provide the needed.
It's not exactly ground floor - you'll have to overcome about eight stair steps. The room is not that bright - there's one window pointing north and two windows (one of them being a big one) pointing eastwards which doesn't help too much because there's a big wall right on the other side of the narrow street. But this, on the other hand, helps the apartment and you to stay cool during hot summer days. The apartment won't heat too fast.
Joao played the role of a professional host. He always was very fast to answer and helped to solve small problems that arised as quickly as possible. During my seven weeks in the apartment, Joao made sure that it was in a good state by having it cleaned every two weeks. I didn't have to pay for that, neither for the tasty cake with cherries his mother brought at the door. Thanks for that!
An in all, I had a very good stay and actually might come back in the future.
