It is a very convenient location of you want to spend some days in Sintra instead of traveling from Lisbon. You take same stairs undergrand and just when you are starting to think you’ve rented a bunker you see yourself into a beautiful detached house with your own private balcony. It is amazing! The rooms are nice and you can do a “kids room” if you travelling with kids as one room has three separate beds. Two nice bathrooms with good shower complete the picture. Just be aware that there are 7 beds. If you hiring for 9 people, two of them will need to be in the couch.
Overall, highly recommend and very very responsive hosts!
