Located in the historical city centre and within walking distance to the must-sees. However, parking can be a hassle (there are some roads nearby where you don't need to pay for parking, if you're lucky). The house is smaller than the pictures make it look, but you won't spend that much time there with all the sights Sintra has to offer. The ventilation in the house is not the best, and there are some signs of humidity on the windows and most corners, so if you are on the allergic-to-everything-side, it may be something to consider.
Nevertheless, the place served its purpose and the host was always quick to reply to our queries, and very helpful. All in all, worth the price.
