We were 12 people and really enjoyed the stay.
The place is quite central, close to the green line at Intendente from where you can get to places like Cais du Sodre really quick.
The apartment itself is in a quiet neighbourhood a little up a hill. Inside there is a kitchen, a living room, five bedrooms and three and a half bathrooms, all furnished quite lovely.
The contact with Daniel, Luis and Susana was really friendly and responsive.
We had a great time and would definitely recommend the apartment to anyone going to Lisbon.
