We really enjoyed our stay here. The location is very close to a metro stop which made it easy to get around the city. There are several shops and restaurants around as well as a grocery store not far down the street. This apartment is on the 4th floor of the building and there is no elevator. This was only an issue for us when we were arriving and leaving since we had to make multiple trips to move our luggage in/out.
The apartment itself is very clean and looks like it has been renovated not too long ago. The hosts were extremely friendly and very helpful, offering advice on what to do during our stay and the local events that were going on.
We rented a car for a few days to travel to Morocco and Gibraltar. The streets are usually lined with cars and finding a spot can be difficult (small spots and most streets are up or downhill) so we had to park a few streets away from the apartment and walk over. Driving in the city is otherwise unnecessary because the apartment is so close to the metro which can take you anywhere in the city.
I would definitely stay here again and would recommend it to others looking to stay in Lisbon.
