This is a really lovely flat with an ENORMOUS back deck - we were floored at the size and beauty of it and wished it had been warmer so we could have used it more. The place is a little hard to find by car - we parked the car and ended up finding it by foot. But it's worth it. Comfortable beds, beautiful rooms and an easy self-check in.
Two things to note: don't drive in Sintra. Cipriana tried to tell me that and I didn't listen the first day. Seriously: park the car and take ubers. But be careful where you park: we got confused and ended up with a ticket. If there is no free space in front of the croissant shop on the same side of the street as the building, leave your car in the ONE free lot we could find: Sintra Parking, Sintra Parking, Av. Dr. Álvaro de Vasconcelos 13. But definitely stay in this flat: the location is easy walking distance to the Historic Center without being in the middle of that highly congested area. We were upset that we didn't stay two nights!
