I stayed here one night to make the drive to Sintra easier. The place is ok for this service, only. I also liked being away from the city center for a night to see what life is like in the suburban areas. However, the larger “mattress” (if you can call it that...) is extremely uncomfortable. I’m certain there was no mattress at all, and instead only the box bed that holds up mattress.
In the separate room the two smaller beds have better memory-style beds (again, not real mattresses... but something you would take camping). I slept on this and it was fine.
If they change the bed situation I would still recommend the home for a night to go to Sintra. Hopefully, they do this for the next visitor.
