The place is possible in the best location of Cascais, next to a beautiful square, next to (just a few meters away) some of the best restaurants in town and a two minute walk to the city center and yet in a peaceful and quiet area.
The common areas of the house are just wonderful and really pintoresque.
The city is really humid and I think in summer would be quite hot, yet the room (and I think the house) doesn't have AC. There was a fan in the room but I don't think it will make the cut in summer.
The room itself is ok, the bed and the pillows, I'm sorry to say are below the level of the house, and I didn't find them comfortables, and the room has some humidity (its form the foundations) and again an aircon would have definitely would be useful.
Don't expect a BnB in the sense of "people" or "staff" it's kind of an Amazon BnB, beautiful, clean and well located, and in the pictures "very human". This lack of real person in the building is greatly covered by Mars who is always ready to help and assist you via message.
Overall is an amazing place to stay in
