Ana's & Hugo's place is lovely (clearly they decorated it with taste) and very welcoming.
The location is perfect, close to metro/bus/tram/train/boat stations and at walking distance from the main attractions of the centres. There are many restaurants, bars and cafes close by and a couple supermarkets too.
Having explored Lisbon for a few days, we honestly could not think of a better area to stay in!
Sadly we did not get to meet Ana and Hugo as they were on holidays too, but they left us their home as if to a friend.
