Christiane's place was perfect! My friends and I loved our stay there. It was centrally located, just steps away from shops, restaurants and things to do. Everything was just as pictured and plenty of room for 3-4 people to stay. It was also a wonderful place to rest and relax in between visits to all the surrounding beauty.
Sintra itself is beautiful. We were able to step out and get a tuk tuk to one of the sights and walked to the other one. We didn't plan anything ahead and were easily able to get around.
Communication with Christiane was excellent. We never met her, but her friend let us in and gave us a lot of information. He owns a tile shop near the apartment. He recommended good restaurants and even let us keep our bags in his shop on the day of checkout so we could enjoy Sintra more. We all bought some beautiful keepsakes in his shop.
When I stay at Airbnb's, I look for the small touches. We were left a small bottle of port and large bottle of drinking water. It was very much appreciated! I would highly recommend Christiane's place for your stay.
