We loved our stay here! It's perfect for two adult friends (and would work well for a couple). The location is ideal, so easy to walk around CasCais and the coast. It's a cheap Uber into the Sintra area, and isn't too far from the airport/Lisbon either. The location is quiet at night and felt very safe. It was a perfect stay for us!
*I would say it's not a great fit for someone with decreased mobility - each room is on a different level with stairs in between. I always add accessibility information for others to know, this doesn't take away from our experience here.
