The communication with Isabel and the check-in was very smooth. Isabel's husband Rogerio greeted us at the apartment kindly. The apartment is located very centrally and is a good start to explore Lisbon.
One of the bed rooms is faced to the pedestrian zone which can be very noisy even in the late evening. If you need silence to sleep it could take some time to doze off. ;)
All in all I definitely recommend Isabel's apartment for your next trip to Lisbon!
