We've ( 3 Persons) stayed in Joãos apartment for a few days while our city trip to Lisbon and really enjoied it. The interior of the flat is so nice and every thing was very clean. Its a bit small, but when in Lisbon you don't spend much time in the flat so it doesn't really matter. The location of the flat is quite central, 5 minutes walking and you are in the center. I really can recommend staying here!
