Great apartment for a family in a very central part of Lisbon. Close to the city centre, but in a small quiet street. The building is old, so you can hear the other tenants and the street, but nothing out of the ordinary, if you're used to living in an apartment.
The apartment is newly restored and is very clean and modern. It has everything you need, even though it is narrow and compact. The only thing to be aware of is the bed in the master bedroom, it is very hard and if you are taller than 190 cm you cannot lie at full length because of a head- and footboard. But there are two softer beds in the other bedroom - so no stress:-)
We traveled two adult and three children (0, 5, 10 yo) and the apartment met our needs, including the extra baby cot and baby chair that we ordered! The kitchen also made it possible for us to make breakfast at home and heat food for the baby!
The hostess was nice and helpful with the few things we needed.
