We spent 5 nights at Casa d Sintra. Well equipped for the two of us. It’s an excellent location for Sintra, the surrounding area and train into Lisbon. The music from the restaurant opposite is quite noisy but was switched off by late evening so ok. Quiet during the night.
Carlos was very helpful in storing our bikes, finding a free parking space and recommending where spaces are found around the town.
Certainly recommend a stay.
