Joao’s apartment is well located. It is a walking distance to most sites of Lisbon, and it is also close to metro and train stations
There are plenty of bars, pubs and restaurants in the area, for all tastes.
But don’t worry, you won’t hear any sounds from the street. You can only hear sounds from other apartments (in our case, it was a baby crying all night, but it didn’t bother us that much, because we were really tired from all the walking).
The only problem we had was with the key from the main door to the building. It wasn’t working really well (there is a note on the building saying that they are going to change the lock), and it took us a while to open the door every time we went back to the apartment.
We do recommend this place.
