The apartment is not really easy to find but Carlos helped us, guiding us through the roads until the free parking (it's exclusively of the building, so it's almost easy to find always a spot during the day). Carlos also has given us some helpful recommendation about the very touristy Sintra.
The apt was really spacious and clean with 10 mins walking distance to the metro and train station. There is also a giant shopping center with shops and restaurant. Definitely recommended!
