All of my family loved this apartment. It is very comfortable and very well equipped. The kitchen and dining room are great. The location is great and just by a metro station (on the same line as the one to the airport). The outdoor terrasse is a little haven within the city, very quiet and comfortable.
The host is very nice and welcoming and he arrived in less than 5 minutes after we arrived at the apartment. He gave us a tour of the apartment and suggested good restaurants in the neighborhood.
I highly recommend this apartment, it made our stay in Lisbon very pleasant!
