We spend two amazing weeks at Frederico's place.
The apartment is great, very bright and big enough for us four. It is also not too far from the center of Lisbon by subway.
Frederico and Adriana were the kindest hosts ever, always available if we had a problem or questions. They gave us plenty of indications and ideas of places to visit in Lisbon. We also had the chance to spend a great evening with them at there place.
We would definitely recommend Frederico's place to everyone !

Ps: We wish you two the best and hope to see you again one day !
