We stayed in the apartment for 4 days. Joao was at the apartment to meet us and welcomed us. We were a group of nine and the apartment is big enough to accommodate another 4 people. Very well located for visiting. We stayed from Sunday to Thursday and there were no noise during the nights. We actually slept really well. Only criticism is the heating system in the cold season. There were only small mobile electrical heaters to heat the rooms. Apparently this is the norm in Portugal as winter is not that bad compared to other european countries. After being out sightseeing all day, you do feel the cold when you get back to the apartment in the evening. Lisbon is a great place to visit, the people are extremely nice and the apartment is perfectly located to visit the city, I would recommend it and definitely go back again.
