Booking direct

Why book without a platform

No commission

No service fee, no platform commission, no cleaning charge appearing on the final screen. The price quoted is the price you pay.

You speak to the owners

We answer ourselves. We know the apartment, the beach, the tides and where to eat. There is no call centre in between.

Room to be flexible

A late arrival, three nights out of season, a question about the beds — we can usually sort it, precisely because nobody stands between us.

I loved the location and how well equipped the apartment is. The housekeeper was very welcoming. I would recommend this place with my eyes shut.

The location is fabulous, (literally) two steps from the beach and close to the shopping street. The apartment is very well equipped, clean, everything you need is there, and the bedding is immaculate.

A lovely apartment. Warm and welcoming. Beautifully placed: right by the water, with the centre two minutes’ walk away. Wonderful walks nearby.

The apartment is very well placed between the harbour and the town, with a lovely view over the main beach, and it is well equipped.

The location and the view from the apartment are fantastic. All the essentials - bakery, supermarket, restaurants and bars - are within walking distance. There is a wonderful atmosphere along the beach promenade in the evening that makes you want to linger.

The area

Saint-Cast-le-Guildo and the Emerald Coast

Seven beaches, a marina, the old customs path starting at the foot of the residence, Cap Fréhel and Fort la Latte half an hour away, and a boat to Saint-Malo from the harbour: Saint-Cast is an ideal base for the north coast of Brittany.
