Apostolos's place truly is amazing, the pictures don't even do this place justice.
Pros: The location could not be more perfect and is a very quick maybe 5 minute walk into the main part of Mykonos town. You definitely don't need a car. The bus stop is also a quick 10 minute walk from the house, so you can get almost anywhere on the island from there. You will also find a 4-wheeler place down the road if you want to rent. The hot tub was amazing and worked great. The views were even better than in pictures. The house was clean and had working A/C. We were pleasantly surprised to find a hair dryer and iron at the house which weren't identified on the listing. Apostolos did a great job of giving us an overview of the town, how to get around, and the best spots to check out.
Cons: We had some issues figuring out checking in as we couldn't initially find Apostolos at the port where he was supposed to meet us. Luckily we had a friend with an international phone plan so once we were able to reach our host we figured everything out. We also had some issues reaching Apostolos before the trip, which made us a little nervous about how to get to the house until we were able to get a response. There is a big hill from town into the home, we didn't find this to be an issue but an FYI for anyone older. We did hear the neighbor's rooster and the dogs in the middle of the night, but that didn't really cause us significant problems sleeping. If you're a light sleeper just bring ear plugs.
I would definitely recommend to a friend - one of our best stays in Greece!
