Silvia was always reachable even though she could not welcome us in the apartment, a friend of her did it. The apartment is very well located, we did not need to use the metro at all. It is a very charming place and spacious. We were 2 people staying, but you can stay with 4 people without any problem, there are 2 separated bedrooms. The bed was comfortable, the kitchen well equipped. I would really recommend this place if you want to visit Lisbon.
