The apartment is spacious and well decorated, and the location is good. The view from the back overlooks the Sintra mountains and you can see the Pena Palace and Castelo dos Mouros while reading a book or eating on the terrace. The pool has a good size and there is a good space to catch some sun and eat meals outside.
The kitchenette, in my opinion, is not ready to cook meals (only one hot plate, that wasn't connected to the power, no running water...) It's more suitable to heat pre-cooked food.
Another thing that I should mention is that there were moments when the apartment had a strong smell, something I've warned the owner about and hopefully will be fixed soon.
