We enjoyed very much our stay at Ilia's Airbnb. The place was beautiful and comfortable, everything was clean and tidy, it was bright and spacious, and the window offered a view that can see the sun set across the town into the sea.
The location was excellent, a little tucked away from the busy streets so that it was calm and quiet, yet if you go down a few picturesque small streets/stairs, you would be right in the middle of shops and restaurants; very close as well to the old port and seaside; also very close to the main car road, which saved us the hassle of hauling our suitcases up and down the stairs of Mykonos. Check-in was easy and straightforward with the lockbox. We didn't really talk much with Ilia (because everything was already perfectly in place!), but she always responded very quickly whenever we sent messages.
I would definitely return if I visit Mykonos again, and certainly recommend!
