We were two familys with 2 year old kids staying at Dagmars place. We absolutly loved our three night stay. The house is lovely and there is a lot of space and things to do (games, play och just relax). The kitchen is well equipped and everything feels very homely. The location is very good as well, close to the train station and walking distanse to all of Sintras amazing sights.
Hope to go back one day!
