I didn't meet Isabelle, and me and my girlfriend were welcomed by Cesar. He was very nice and attentive and told us about some touristic points in Lisbon. The apartment is just like the photos. It is very confortable and the view is very nice. The Alfama neighbourhood is full of options of restaurants and little markets and it is very close to the city center (10 min walk to Praça do Comércio). The apartment is also next to the Santa Apolónia subway station. I would certainly stay here again.
