The apartment is perfectly big to accommodate 9 people. It is very well located, with a Metro station very close to it. Also, there are supermarkets and restaurants and shops around. Very convenient for a great stay in Lisbon.
The area around is full of parks and places to visit.
The building neighbors are extremely kind and helpful. Internet is fast and reliable. The nearby streets are full of offices and so, at night, there is no street noise.
Beds are comfortable and the kitchen is very well equipped.
I would recommend it for large families or group of friends.
