We had a fantastic stay in Maria's palace. The house itself is very historic and interesting. Its in a quiet area of Lisbon but very close to all the touristic areas and great for transport links to Sintra. We were give a tour of the grand part of the house which very interesting. Although the showers and loos are shared they are spotlessly clean and numerous so there are no issues about access, the shared areas for dinning and living are spacious and modern. We would really recommend this air bnb, it was great value.
