This is a very good size appartment with plenty of space to relax after all the buzz of Lisbon's busy streets, with everything you need. The location is excellent to catch the bus to and from the airport, and there are supermarkets (and even markets) within a 10 min walking distance, not to mention the proximity of the seaside only 2 min away!
Night time can be a bit noisy as the street below hosts tramways, buses and cars, but this is from people that do live in a quiet house so we probably have forgotten what it is like to be in the center of a busy capital.
All in all we had a very good stay and would highly recommend Sandra's place.
