I stayed with Pascale for 10 days. It was an ideal spot in a neighbourhood with a one of the nicest largos (local plaza) in Lisbon, with several cafes / bars, restaurants, small grocery stores nearby. The metro is only a 5-7 minute walk, and the tram is also very near. The Castle, Alfama, and the riverfront are all 10-15 minute walks. You're in a local neighbourhood. Very convenient.
Pascale is wonderful, and her place is ideal for one, or a couple to stay in. You have a nice room, with it's own entrance. The rest of the apartment is shared.
