João and his wife were excellent hosts. They were very friendly and very accommodating. I was running late on arrival, and they helped by staying over a bit longer and giving me instructions on how to but metro tickets and where to go. Their place is very homely and in a very typical Portuguese neighbourhood. Very close to the Metro station, and I was even able to walk to most of the venues in Lisboa, including the Castle and the main Praça do Comercio. They were easy to get hold and bent over backwards to make the stay enjoyable.
