Double-booked but mistake handled properly:
There was some mix-up or double booking, because a day or two before we arrived Marianna sent us a message that she had booked us a hotel room nearby her place. So a little strange having to figure out the new place to go to on short notice, but she handled it professionally booking us a comparable place and taking care of that. 4 stars for that.
A note on the Location:
I think Marianna's place was near the town of Ornos, not too far from the hotel we stayed at, GIANNOULAKI, and we found it quite stressful to take the public bus from the port, and then walk uphill to the hotel. The roads are quite scary to walk as a pedestrian and the heat was brutal in August... for 2 Canadians at least... 😄 If you're in Mykonos and you're staying in a hotel you're clearly not poor -- do yourself a favor and get a taxi/shuttle/rent a car/atv etc. and drive to /from your hotel.
