We stayed with my girlfriend at Frederico's apartment for 3 nights. The apartment is exactly as showned in the pictures and described. It is very very clean, cozy and really bright during the day. It is so centrally located that you can walk everywhere and return easily if needed at any time of the day. Everything you want to see and go in central Lisbon is so much close. It is also 50m away from Metro station and few meters away from station of tram 28. Also, I would describe Frederico and Joana as super hosts as Frederico was so willing to eagerly help, promptly answer to questions and communicate with me at all times needed and Joana was there to wait for us and wormly welcome us with a sincere smile to the apartment despite our long flight delay which cost our late arrival. These guys made as feel as home!
I strongly recommend this place and of course Lisbon itself! I wish we could return!
