Late night arrivals or leaving were not a problem. Host was really attentive to our every need. We got complimentary breakfast.
Place was perfectly clean, spacious with every amenity required even for longer stay. Even wifi internet connection and TV.
It is situated in nice quiet suburb part of Lisbon. 10 minutes walk from big mall with cheap grocery store. The nearest metro station is same 10 minutes walk. There is bus stop right in front of the apartment building.
Even when there are strict rules about silence after 22:30, we had no problems with regular talking, cooking or listening music.
