We stayed in the apartment for three weeks. The place looks identical as seen on the photos and has every amenity that is listed. The only thing that could be improved for longer stays would be a couple more towels as well as a second pair of bed linen.
All in all we had a very good stay in the apartment and would definitely recommend staying.
Extra plus: you can also use the air con for heating. Lisbon in January can be pretty cold 😄
