This is a very well kept Airbnb. All new, maintained and very clean. The home is on a hill so have no concerns when you descend stairs to the living space. You are not going to a basement unit! We enjoyed the backyard as we decompressed from our excursions in the area. We walked to get groceries at Pingo Doce It took 20 minutes to walk to the Airbnb ( up down hills which is typical of Sintra) . Transportation is needed to go to the old city. We hired a company to show us Sintra and the area around it so no problems for us. Owners live in number 23 while the Airbnb is 23a. We did not see them or hear from them except to welcome us via the Airbnb message system. Would recommend!
