This is a beautiful villa with plenty of space set apart from the touristy spots. 14 of us traveled here from different parts of the UK to have a friend holiday and we had a great time. The villa is pretty isolated but it means you have a beautiful private beach to yourselves and don't have to contend with noisy neighbours, blaring music, or screaming children. I highly recommend hiring cars though, as we did, as it means you can travel very easily to any sites, historical towns or places to eat.
The air con in the rooms is fantastic, and all windows have black out shutters so you can have a lie in without being woken up by the sun. We didn't have any hot water in the mornings though but I think that's because the water is heating in tanks on the roof with solar power.
There are loads of appliances such coffee machines, toasters, microwaves, plenty of cooking dishes and a good oven / hob - we couldn't understand the washing machine though because it's in Greek.
I wouldn't have wanted to have any more than 14 people though because the outside table only seats 10 and the 15th bed is only a day bed in the kitchen / dining room. Extra door keys would also be very useful because the doors automatically lock and the key is attached to the card that makes the power work. This means that if you split into groups, if one group has the key the others can't get in the house or use the lights - the upstairs also automatically locks so if someone is in there having a shower or a nap, you can't get in without banging on the door.
