We had a great stay for 6 nights at this studio apartment at the end of July 2022. We had been worried about the heat considering there was no air conditioning in the apartment but Sintra is a relatively cool place and windows front and back provided excellent cross ventilation when needed. Black-out thermal curtains blocked the morning sun on one side and afternoon sun on the other side when needed. The location of the apartment was great being that is is close to the grocery stores as well as to both train stations. Internet was great, bed and furniture were comfortable, and basic supplies were provided. We would definitely rent this apartment again if we were ever to come back to Sintra.
