I booked Paula's apartment for my parents. They thought it's very comfortable, and they enjoyed their stay. The flat was fully equiped, decorated with taste, and very clean. There even was a little gift waiting for them !
The flat is very well located : 15 min to walk to Carcavelos beach, in front of the train station (less than 20 min to Lisbon's center), and in a free parking zone.
My parents and I would come back to Paula's place with great pleasure !
