We were there with 2 adults and 2 kids. The accomodation is complete. A little bit small with four, but this is compensated by the huge garden. It's very quiet during day and night. There are some frogs and seagulls that can be noisy, but only for short moments. We slept with the windows open without problems.
With a few minutes walk, you reach the railwaystation at the beach and you can go anywhere (bus, train, car-rental).
We rented a car : there is a plenty of parking space close to the flat (free of charge)
Monica is very friendly, gave us tips at the beginning of our stay and was available for information (whatsapp) during our stay. She's open to suggestions as I saw that most of the remarks of previous comments were dealed with.
