We had a large group (max size of 13) stay for 6 nights at Annita and Chris's villa and had an incredible time. The villa itself is as large as it looks in the photos and the pool, pool deck, and grounds are even better than they look in the photos! The daily cleaning service was a huge plus being such a big group, there were enough sleeping spaces and bathrooms for all (although if you are 13 keep in mind that two will end up on the couches in the living room but they are perfectly decent for sleeping on). I think one of the best elements is the privacy. The villa is just far enough from the town centre (approx 10 min drive) that you feel secluded. It's also directly on the sea (with a view of Mykonos town across the bay) and you don't see any neighbours for three quarters of your view from the pool area. You will definitely want to rent cars or atvs to get around safely as the roads are unsafe for walking on in my opinion (we rented 3 cars and didn't have many problems finding parking in town or at the beaches). Host is very responsive and helped us with all of our questions promptly before and during our stay.
Thank you for a memorable Mykonos experience! Highly recommend and hope to return someday :) !!!
