What a wonderful experience in Sintra! Lisa's place is a 3 story guesthouse with 2 remodeled apartments. We stayed on the apartment on the top floor, with great views of Sintra's old town and a bit of the Moorish castle. It's also in a GREAT location - 10 mins walk to the train station and the start of trails to walk to all the famous sites. 5 mins to several restaurants and 10 mins to a grocery store. No car needed! And if you are tired out and want to relax -- the garden is a peaceful oasis for a nap or cup of coffee.
Lisa was welcoming and answered all of our questions during check in and throughout our stay. She tailored our experience and recommendations (local restaurants, how to get to Pena Palace and the other sites, day trip outside of Sintra, etc). One of the best Airbnbs we've stayed in.
