We had a fantastic week’s holiday in Sintra. The hotel was perfectly located for a stroll into town and easy access the great restaurants, cafes and the sights of Sintra. Brill ice cream from Mica’s just outside the hotel. Easy train ride to Lisbon and the beach for day trips. The staff were very helpful and excellent service in particular Joao. We enjoyed a lovely breakfast full of choice everyday ready for hikes and touring about.

Our apartment was absolutely amazing and as stunning as the pictures. Perfect with our three year old who called it our 'home-tel,' Our flights were delayed on the way out, I was able to call through to reception who provided us with access to the property after reception hours with really clear instructions. We just loved it so much, will definitely be back.
