Sofia's place is a great find in Mykonos. There's a busy road that separates this apartment from "downtown" Mykonos, if you will. It's pretty easy to cross the street though, or there is also a path down some steps that goes under the road.
There is a mini mart about a 5 minute walk away which has just about everything you will need.
As for the property itself, it's better than the pictures show. The building is surrounded by a stone wall and fencing, which makes for a beautifully cared for courtyard, trees, plants, and flowers. I wish we could have seen it at night with the lights on, because it really is stunning! Do be careful to keep the doors and windows locked when not at home. Mykonos is a lot of partying, so like any place with that kind of crowd, just take the extra steps as a precaution.
Sofia was very quick with her replies. It's not really a named place such as a hotel for a taxi to easily drive you to; but Sofia gave us the GPS coordinates, and they were spot on. Our ferry was delayed, and Sofia's carer was flexible with meeting us in person at the property.
I would definitely stay here next time in Mykonos!
