We had a fantastic time at Sergio's beautiful apartment. This is probably the best AirBnB I've stayed at. I really really liked the minimalistic, functional and beautiful style of the apartment. It has everything that one needs in order to live comfortably. The view from the living room is magnificent. The location is also really nice, being close to the historic center, the main tourist attractions, as well as a variety of delicious places to eat. Catarina, who welcomed us in the apartment, was super friendly and nice. Last but not least, Sergio's famous guide is a real gem, sparing you hours of research and providing you with all the essential info that a tourist would need in Lisbon. If I return to Lisbon, which I hope I will, I'll definitely try to book Sergio's place.
