Ana and her family were fantastic hosts, always available to help and very accommodating.

The apartment was immaculate and they had thought of just about everything you might need for a comfortable stay.

Only slight issues were the location of the apartment and some noise. The location although central is up a quite large hill which requires using the funicular, bus or a testing walk to reach it. But once you understand the buses etc. they are easy to use and we managed the walk a few times with the stroller.
The noise was mainly from the building work, but as we were out most of the day it didn't really bother us and obviously when they finish building it will stop.

Don't let these things put you off, just bare them in mind. Lisbon is a great city and you won't find better hosts.
