Anne, I didn't notice your first post. It's not as close as the simpson villas to the sea, and it's not on the east coast so to me 2100 euro per week is daft. However the owner has come back to me and says the price is the same for up to 10 people, so for a larger party it would be great value.
We are staying at nissaki this summer not far from the beach, 2 bedrooms, 3 bathrooms, pool and gardens etc, £1800 for two weeks including flights and car (would be £2800 for four).
I've booked privately for a decade, but earning less now than I was two years ago and have a pay freeze for the next 3 years as do many others, so if a tour operator works out significantly cheaper, I'll book with them.
