This is a lovely place to stay - I was met by Kika who was very friendly and kind. The house is beautiful with a nice front garden (not overlooked) where you can read. Also it's immaculately clean throughout.
Kika met me when I got back in the evenings and gave me tea and biscuits - I felt very welcomed and taken care of!
The room is a decent size with a big chest of drawers and hangers.
The only drawback is the location - the area is quite hilly so not easy to walk to, but I got taxis into Cascais and Estoril - took about 10m and cost €5-7.
Would definitely recommend!
