We had a lovely stay in Praça de Figueira for 5 nights. The location is perfect, right by the bus, metro, train and tram stations. Most places in the centre of the city are very walkable from the apartment if you are OK with big hills! There are a few places for food and drink in the square but the best places are plentiful around other parts of Lisbon. The apartment is a studio so there is little privacy but perfect for a couple or on your own. It is small but it has absolutely everything you need and the hosts were very helpful providing everything we would need to cook. We didn't because there was so much to do and see in lisbon and so many lovely places to go and eat. I would highly recommend this place to stay if you are going for a week or less.
