Christine's apartment location is superb! Within walking distance of Cascais train station, supermarkets, restaurants, etc. Bus stop (#417) to Sintra is right there as well.
Apartment is cozy, good for 2 pax. Comfortable bed, hot water for winter time, hot/cold air conditioning, towel heater in the bathroom and extra towels and blankets available in case you need.
No neighbors windows visible from inside the apartment, which gives great privacy.
Note that it's access has 2 flights of stairs and no elevator, which is common anywhere in historic town.
Communicating with Christine was easy, she was flexible and made check-in/out process easy.
