We had a very nice stay at Cristina's place. The communication was very good. The house is large and has plenty of space. For children it is really nice with 2 swimmingpools (inside and outside) and the beach around the corner.
It is close to Lissabon, Cascais, Peniche, Sintra, Óbidos et cetera. So there are enough possibilities to explore in terms of culture, beach and surf. We definitely recommend this house.
