I can only agree with the others - this this place is perfect for our stay in Lisbon! Right in the middle of Chiado.. Walking distance to nice restaurants and to barrio alto for drinks and also to chiado for all the shopping :)
The communication was very smooth - Ana and Paolo always answered all our questions really fast and took time also to explain things. We were welcomed with pastel de nata and port wine and on the last night they checked if we need taxi for the departure - very nice gestures. All in all my parents and I had great time in Lisbon and the next time we're back in town, I'll stay at Ana and Paolo's apartment again :)
