John is such a nice and friendly guy, he made us feel comfortable and completely at home.
The building is very charming and the flat has been refurbished recently, so you can't complain about anything.
It was our first time in Cascais and John's flat indeed was a perfect choice for us, it's within a walkable distance from the old town, the Cascais Market, the beach and the groceries stores. There are lots of restaurants around and a nice Portuguese bakery less than a 100 meters from the building.
If like us, you decided to use Cascais as a base for day trips in the area, John's spot is perfect, it has private parking, so you can enjoy Sintra and the other cities during the day, come back and enjoy the evening in Cascais.
The apartment is spacious enough for 2 couple. We stayed there with Izabella's parents and had a great time. I definitely recommend you to stay there and hope you enjoy as much as we did.
