The apartment was clean and the location is great (well connected with the tram or by foot, c. 25min to city centre). Hosts are great and flexible with the check-in time if the apartment is not booked the day before. Only issue worth mentioning, is the fact that the apartment is not really sound proof, so you can hear when someone is walking in the flat above and when they exit/enter the house. However, this seems to be a flaw almost every house in Lisbon has.
In general, I would recommend this apartment to my friends/family.
