This place is lovely! Diogo and his sister are great hosts! No problems at all when our plane was delayed and we arrived later than expected. Diogo is full of local knowledge and was even kind enough to drive us up the hill to the castles and and gave us tips for visiting the rest of Sintra. Their house was lovely and comfy and clean. There kitchen is on a pretty terrace (great place to drink your morning coffee)! Diogo also owns the bar downstairs which is a cool place to hang out, have a few beers and meet some of the locals. The decor is lovely - especially when you learn he did it all himself! Sintra itself is an amazing place. Most visit it as a day trip and it definitely merits at least 1 night. We loved it so much we changed to a later train back to Lisbon to have a bit more time but given the chance, we'd have happily stayed a 2nd night :) Highly recommend.
