I'm helping lovely BIL to surprise his longterm GF with a holiday in the coming week or two. They are looking for a holiday cottage for five days/a week in either Wales, Sussex or Somerset (possibly Cornwall) and preferably near a beach for coastal walks. They want fresh air, to cook food, read books, don't need nightlife. They are both recent postgraduates so are on a tight budget, but would like somewhere clean, comfortable, sleeping two, no pets. We've been trawling through the usual websites but most aren't really geared towards last minute. Also wondering if there are last minute rates for holiday cottages. Any thoughts to help our search go more efficiently?
