We were 3 adults and fit very well in the apartment. It was very clean, it is close to groceries stores, restaurants and a cafe 2 min away where you can have your daily breakfast. We walked daily to the center - 20-25 min, depending of the point of interest. Taxi is also affordable from downtown (3-4euros).
We had a very good communication with Joao and the check-in was very easy, considering we arrived in the night.
Highly recommended.
