The apartment is really wonderful: lovely decorated, well equipped, close to a metro station, a super market, a train station and a post office. It also has 2 bathrooms which is pretty good if you travel in a big group.
Renata is a very lovely and helpful host, she provided us with all necessary information.
If my friends decide to go to Portugal, I would definitely recommend them to stay in Renata's flat! We had an unforgetable time in Portugal! Thank you very much, Renata!
