We had a very nice stay at Teresa's house. Less than five minutes from the main station of Sintra, it has a great location, far from the noisy center but don't worry, everything is still easily reachable on foot. The flat itself is great with a big living room, cosy bedroom, full equiped kitchen. The only thing we were surprised was the humidity from day 2 because as you may know Sintra is located in the mountains and quite often, in the morning, the town is literally eaten and hidden by the mist which I believe can create this humidity inside. It's not annoying if you bring the good clothes and it did not have an impact on our stay. Therefore we highly recommend Teresa's cute house !
