My flight was delayed and I wasn't able to arrive till the next day in the morning. I was worried because in some AirBnB you need to specify exactly the arrival time, but they were available to welcome me at anytime. I haven't meet Stavros, but both the woman who owns the house and the woman who arrange the rooms are lovely and welcoming.
Rooms are confortable and clean.
There is a bus every 30 minutes to get there (it takes 10 minutes by bus from Fabrika bus station, in the city center). Beach is also close to the appartment, 4 minutes by bus to Platis Gialos beach. Bus line works till 2 a.m., at least in September. Once you get used to Mykonos traffic, you can also go walking to some other beaches directly from the appartment.
