With 14 friends we have had a great stay in these apartments. Location was perfect for sightseeing and there are plenty of bars and restaurants nearby. The rooms were clean and all necessities were provided. Since the apartments are in a residential building, you cannot make too much noise during the nights. This is not an issue since the street and area are vibrant at night, so it is nicer to have a drink there :)
Plenty of vans are provided, so despite the lack of an airco it was never too hot inside.
This is a great place to stay with larger groups when visiting Lisbon!
