Looks exactly like the pictures. Myrsini is very quick to reply to any questions, suggestions, or problems that pop up.
It's about a 5-10 minute walk just about anywhere you want to go in Mykonos Town. It's on a hill (as is everything outside of the port) so be prepared for a little uphill/downhill walk.
The place is very quiet for Mykonos. There's a nice little patio that's great for a drink, bite to eat or work space.
Overall it was a great experience, and I would definitely recommend it.
