We spent a very pleasant two weeks at Villa Calypso. The villa is lovely, with fantastic views over the bay. We sat most mornings eating breakfast on the terrace trying to spot the dolphins which you can see from time to time. The pool is raised above the villa and is in direct sun most of the day, as a result it's beautifully warm and lovely for a refreshing swim at the end of the day once the sun has gone behind the olive trees. It was very clean, well maintained and also has a lovely view of the bay. The rooms were very nice especially the front two that have terraces facing the sea.
A few small minor annoyances, no shower curtain in the small bathroom, no cleaning materials at all and it would have been good to have a decent mop, bucket and broom. The barbecue had no proper grill which meant searching around for rocks to be able to raise the food above the coals when we tried to use it. Fixing these small issues would make the place perfect.
The villa is about a 15 minute walk down the hill to most beautiful beach at Nisaki, where there are three tavernas (our favourite was Mary's, we ate there several times). And a short drive up to Athni and Vitamins restaurants which are both outstanding. We rented a small boat at the Nisaki harbour a couple of times and spent days pottering around the local beaches. The sea is lovely and warm, very safe for kids, and excellent for snorkelling.
Highly recommended, we may be back one day!
