Renato's place is about 10 min outside of Sintra via car. We rented a car, so it was perfect for us as we spent the day exploring Sintra and spend the night here. You have to meet up with Renato to get the key and once that is done; it's easy to come in and out. There are 2 beds in the room we stayed in. Wifi worked well, bathroom was clean. Good local restaurant nearby.
