We enjoyed our stay in Costa da Caparica very much. We highly recommend this apartment and its owners and here's why:
The town is located by the ocean shore within close distance to Lisbon. Numerous great beaches within proximity. Very good spot for surfers. The apartment is 5 minutes' walk away from the beach. There are two grocery stores very close which open till late, as well as a pharmacy and multiple restaurants around, most of which are by the coast.
For those without a car, you may commute by public transport to and from Lisbon. Taxi service: Uber is also possible (from Costa da Caparica to the Airport in Lisbon, we paid approximately €20).
Spacious apartment, very well equipped for everything one may need during holidays. Nice kitchen with utensils, modern bathroom. Two double bedrooms and a sofa in living room with 2 extra sleeping places. A big terrace. Very clean.
Very nice, flexible owners. We got an early check-in. Contact was not a problem: Pedro was in touch with us since we landed in Lisbon. He was very glad to help us and explained everything in detail.
Overall, it was a very good experience and we would recommend it to anyone willing to visit Portugal.
