Our stay in Goncalo's apartment was great. Lisbon is a beautiful and magic city and Alfama is the perfect place to stay if you want to feel the proper traditional Portuguese lifestyle. The apartment is 5 mins walking from the metro station that will bring you to the airport and 10 mins walking from the Praca do Comercio or the castle. And you can find many typical Portuguese restaurants and mini markets in the streets nearby.
The apartment has everything you may need and is also well prepared for cold days.
Goncalo was very friendly, helpful and approachable and also flexible with us as we he let us check out a bit later.
I'll definitely recommend your place to my friends!
