We rented an apartment for the whole September and it was a great time. The apartment is located in the center very close to the square and the palace of Sintra, where there are many restaurants, cafes and most of the attractions, it was very convenient for us because we like to walk. From the window we had a good view, and despite the proximity to the center it was quite quiet.
Also in this apartment it was very clean and neat, and the cleaning of the apartment came to us every week, and it was also very convenient for us.
Thank you very much Burkhard and his wife!)
