The stay at the appartement was amazing, Sérgio is a very dedicated Host who tries to do everything he can to make your stay as pleasant as possible, he even gave us a tour around cascais on our first evening, which was very nice.
The location of the appartement is also ideal if you want to go climbing at the local crag. Its just a 20 min walk there but you are also not to far away from dowtown Cascais.
