Hi All,
I stayed at Ricardo's place for three nights. My flight was really late, and Ricardo organised a transfer for me for a ressonable price. He is very good host, who knows a lot about the city and can give you hints.
The location of the apartment is super, it is close to the main train station (if you want to go to Sintra, like I did) and there are several tram stops near and a metro. The apartment is clean and nice, with all necessary staff. I would definately stay at his place next time as well.
BR,
Gulnara
