Superb location in central Cascais. No street noise, but right on a nice shopping street, almost on top of a simple, nice restaurant. Five min walk to station with frequent trains to Lisbon, and five min to beach. Car not necessary nor recommended.
Nice, cosy apartment, spacious for two adults, two young children. Beautiful terrace. Clean and well equipped, including a nice coffee machine with first set of capsules, and various other things which make the first day nice and easy. Dishwasher and washing machine.
Only downside were some of the technical installations. We had a minor flooding from the washing machine, and a broken heater, but this was dealt with the same day by Rita's husband. Some sockets are loose/show wires, I would not recommend the apartment for toddlers, but no problem otherwise.
Rita was very responsive to any questions we had. We had a great holiday, the apartment is great value.
