Our experience with Francis and Izumi was great. Sintra is a great city to visit while in Portugal. You can do the wonderful hikes up to Pena and the Moor castle, along with some fantastic walks through the city and more. The room was perfect...clean, great view, nice bathroom. There was a nice garden area that weren't able to take advantage of due to our timing but it's a perfect place to relax. We also recommend going to Raposa for dinner. Great little spot in town for those who enjoy culinary treats. We'd stay at this air bnb anytime.
