We stayed in Antonio's apartment for 6 nights. It is centrally located for most major attractions in the downtown of Lisbon and near the metro and bus stations.
The apartment and backyard are larger than what shows in the picture. We loved the amazing apartment, and enjoyed drinking or taking a nap in the quiet backyard.
Antonio is a nice and responsive host. He gave lots of suggestions on restaurants, supermarkets, bakeries, parks, etc.
The apartment is still my first choice if I travel to lisbon next time.
