The flat is ideally located in the middle of Sintra. The seating area in the garden is lovely however the entry is via a series of gates outside the flat because the main access is for the flat below. Izumi was very kind and helpful and extremely welcoming.
Izumi mentioned the problems with parking but we underestimated how serious they were. You will not be able to park near the flat and Sintra is a maze of one way streets which makes for very long detours if you get lost.
This place is a perfect place to stay in Sintra but we would highly recommend not taking the car.
