Lovely apartment in the heart of the town. Restaurants and tourist attractions are close, so is the train station if you want to do the day tour to Sintra.
Everything is clean and comfortable, arranged with a personal touch, the hosts are accommodating and helpful. Pick-up, giving a hand to get the bags up the stairs, making taxi arrangements for going back to the airport, providing sightseeing and dining tips. And the pocket wifi comes as a great plus.
Only be aware that the bathroom and shower are really small, as you can see from the photos.

Overall: absolutely recommendable.
