Rita is a phenomenal host. She was welcoming, sent us several suggestions for our stay and even let us check in early. It was great to be so close to Sintra and the views and town was absolutely adorable. The place itself is clean and modern with all amenities we needed.
Unfortunately, the house is located right on one of the only streets leading in to Sintra, making it very busy day and night. Sleeping on the sofa bed in the common area we were woken up every 5-10min from large coaches and cars passing.
Not sure if we hit a very unlucky time (late September) with lots of tourist buses, but I would suggest only staying 2 people so you can all sleep in the bedroom, or providing ear plugs to keep the noise out.
