It’s a cozy spot perfect for a couple. Warm shower and comfortable bed, and well located to the attractions in Sintra. The little patio out back is a nice place to relax. There is internet although it was a bit slow when we were there. Good and timely communication with the host.
You can easily walk to many of the attractions (Quinta, Palacio, etc) if you don’t mind walking on some roads without much of a shoulder. You could, however, take a tuk tuk instead.
I don’t recommend this spot for four people, because although the sofa bed is surprisingly comfortable, it is by the front door and very close to the main road running through the area. This means there is a lot of traffic from about 7am-10pm and also some cars and trucks throughout the night. So the sofa bed is definitely not as peaceful as the bedroom, which faces the back and wasn’t affected by the traffic noise.
A good value overall for a couple staying in Sintra.
