I stayed at the apartment of Maria and Filipe with my brother and sister. It's a really nicely decorated and clean house in the heart of Alfama. Maria and Filipe were very nice and welcoming people, taking the time to show us around and giving nice recommendations for things to do in Lisbon. The apartment is perfect for a couple, but staying with 3 is also possible as they have a sleeper couch in the living. Thank you Maria and Felipe, we really enjoyed our stay!
