The place is as discribed and the location of the appartment is great to visit Cascais.
However, it is very loud IN the apparment with noise coming from literally everywhere: neighbours, entry door of the appartment, etc.
In addition, it's impossible to get the room really dark as there is an issue with the shades and it is very bright in the room.
All in all, good place to stay for activities in Cascais but you need a very very deep sleep...
