The apartment was well located. In the alfama quarter, it allows you getting to most of places in Lisbon. The metro is really near. At night, It is very peace, no noise.
Regarding the house itself, it is really for 5 people, we felt confortable and ill at ease. There are pretty much everything we need in terms of equipment for a long.
Finally, Joao was very nice. We arrived at night, and he was there to welcome us.
Our 7 days stay in Lisbon has been incredible and amazing.
