Joao and his wife were very friendly hosts. They helped us with recommendations for Lisbon, and with ordering a cab to the Airport.

The apartment is located very conveniently, close to the most interesting neighborhoods of the city. The immediate neighborhood is quiet and charming. The rooms are not super sunny, but that makes the apartment perfect for the hot summer weather. The subway station is a no more than a few minutes walking away. For those in need: There's two great vegetarian restaurants very close by.
We really enjoyed our stay and can recommend this accommodation to anyone.
