We had a very pleasant time in Quentin's apparent.
It is quiet easy to find, but the stairs leading up to the living area are very very steep. Be prepare for that. ;-)
It was easy to get to the flat via public transportation starting at the airport and Quentin gave us a great plan on how to get there. Looking for a perfect starting location for daily tourist trips around Lisboa, this is the place where you want to stay. That is because it is in a very central place in the city. Food, drinks and lots of history are all around you.
It is small, but very clean and for a short trip to Lissabon highly recommendable. For another trip to this city we will try to book this apartment again.
