I really enjoyed my stay in Maria's house. It is located in Alfama, which is the coolest and most traditional neighborhood of Lisbon with many nice restaurants and bars close by. The apartment is very clean and the bedrooms as well as the bathroom are in perfect condition. Maria is also easy to contact and responds quickly if you have any questions. The only small downside might be the fact that there is no elevator, but you can't expect this in a traditional neighborhood like Alfama. I definitely recommend staying here if you want to visit the great city of Lisbon.
