We are a family of four with two teenagers, and spent a week in Portugal using this apartment as our base. The apartment is located in a residential area in the hills above the center of Cascais; it takes about 15-20 minutes to get to the center and the beach on foot, but there are also local buses that stop close to the apartment and take you directly to the center. From the train station, there are frequent trains to Lisbon.
The apartment was recently renovated and is furnished in a unique style. It is also quite spacious and equipped with all the necessary amenities, even for longer-term stays.
All the information we needed was provided both in electronic communication (emails and text messages) and in a printed form in the apartment. The hosts and their helper Diogo were very friendly and provided assistance in every aspect of our stay (including late check-in, transfer etc.).
We would definitely recommend the apartment to anyone planning to stay in the area.
