We stayed at this house last year and immediately booked it again for this year. The house is spacious and has everything you need, especially for a holiday including small children - a big sunny garden, crazy golf immediately next door, 2 minutes walk to ice-cream, 5 minutes walk to a swing park etc. It also has its own parking for at least 2 cars.
St Valery itself is a lovely town - bars, restaurants, steam train, boat trips - all within easy walking distance of the house.
Sunday mornings a big food/clothes market sets up between the house and the town centre - buy a roast chicken for dinner!
