highly sincerly reccomended Nuno's house/rooms! I was there for only few days but really enjoyed my staying: right in the heart/city center of Lisbon, easyly connected with metro and public transportation and very near to almost all in the city center. Then Principe Real is wonderful as area, and right nearby you have Barrio alto, rossio, chiado and the main areas of the city. Then Nuno is the perfect host: he wasn't there when I arrived but organized perfectly to make me feel welcomed and comfortable, the house is clean, very nice, comfortable and he is helpful and friendly.. very very advisable :)
