Luis and Paula are nice people. My family and I stayed 3 nights in Lisbon. The apartment is well located. However, we were not that satisfied with our stay. The check-in was later than we than what it should be! we checked-in at 17:00!!
The apartment wall is so thin, therefore, we could not sleep because of so many noises of neighbors and people out there (regardless of the place is located on 3rd floor). There is no elevator and the stairs are so tiny and high, and they are wooden! That is why they have load noises! It was so difficult to take our luggages up there! The apartment itself is tiny and for 5 people there is less place to walk. Absolutely not recommended for families!
