The flat is very very close to the sea and approx 5-10mn walk from Cascais station. Very close to plenty of restaurants (either in the center or in the small streets around). The double bed and quilt were very confortable. The sofa bed in the living room can accomodate one person. The flat was as described in the pictures. Maria was very helpfull: answered our questions, met us to check in, recommended some places.
We didn't hear the neughbourghs at all, a bit of noise from the street but nothing major.
Would definitely recommend Maria's flat for a stay in Cascais
