We stayed in the appartment for 4 nights.
Helenas husband picked us up at the airport and made a little guide tour on the way.
The appartment it self is perfect for two persons with everything what you need for a short city trip. It's really close to bairro alto (nightlife) but in a quite neighborhood so that you hear nothing. Walking to downtown is a little longer but definitely doable. We never took the sub to get around in the city, everything is in walking distance.
So if we come back to Lissabon we would choose this cute appartment again!
