We had a great stay in Lisboa at Feliks's apartment. We didn't meet him personally, but the communication was seamless. While the street itself is still a bit under construction, the location is minutes from so much: restaurants, shopping, bars, and historic areas. We particularly enjoyed exploring Castle Sao Jorge and the small side streets up and down the hills. As other reviews have mentioned, you do hear people on other floors (there was no partying, but it was just an old building with wood floors that don't block the noise). The flat itself is really nicely arranged, and there's just enough room on the balcony to enjoy a cup of coffee with fresh air. We only regret we had limited time to stay!
