I'd never been in Portugal and to be honest I fall in love with the area of Sintra. All the palaces, park, beaches and villages it's a gorgeous place. You have a lot of things to do but fortunately we rent a car because you really need it. About the flat, it was very pleasant, comfortable and modern and we love to be in a calm atmosphere. Plus, the lovely terrasse is perfect when you want to eat outside or just have a break in tranquillity.
I commend this place if you have a car and you want a cosy house for you. (The dogs were so cute).
