We stayed with Ana and Bernard for a few days and right from the start they were brilliant hosts. Although their place is about a mile from Sintra historical centre, they offered to give us a lift every day, even texting us in the evening to see if we were ok and if we wanted a lift home. Although we had our own space they were also great company and invited us to share a drink and talk with them when we felt like it. They had great local knowledge (Bernard working as a tour guide) and they went above and beyond to accommodate us and make sure we had a great time with them. I feel like I have made some great friends and am already planning my next trip to Sintra in my head.
p.s. there's use of a communal swimming pool which isn't mentioned in the ad.
