Superb location; the apartment is in the middle of everthing, you can reach the main touristic atractions within 10 mins which made our visit to Lisbon really practical.
It is located in a pedestrian street but it is not a nosiy area at all.
The apartment itself is spacefull enough for five people, it looks like as it is shown in the pictures, and beds were very comfortable.
Wifi conexion did not work very much and if you are planning to cook the kitchen may be a bit small, however it has the necessary kitchen utensil. (It does no have dishwasher though).
Conunication with Martha was super easy and all were facilities to make our stay perfect.
I would recommend the appartment specially becouse of the location, it could not be better.
