I really enjoyed my stay at Fernanda's! The room is as it is in the pictures and it comes with a private bathroom. The entire area was very clean and Fernanda was very welcoming and helpful. On the day of my departure she let me use the beach towel and leave my suitcase at the property until the late afternoon.
The location is absolutely fantastic (the flat is right in the centre, close to bars, restaurants and the beach). I was traveling on my own and it felt really safe even late at night. Would definitely recommend staying there! Also, perfect if you want to visit Sintra, as there are direct buses leaving 5 minutes away from the flat.
