This is probably one of the best locations that you could stay in Mykonos. We went during an off season so not many places were open, however, there was just enough stuff to get by during our visit, and we really got to enjoy the true beauty of the island. The location is so perfect, walkable to everything you will need and the best sunset location! Alexander was very responsive and always provided good recommendations.
One thing to note regarding the provided taxi pick up, it is extremely expensive (50euros for over 2km ride, approximately 7 minutes). It was my fault for not checking the distance beforehand but it was very unreasonable in our opinion, unfortunately we only found out after drop off. So if you could find a taxi upon arrival, it would cost you between 15-20 euros.
