Great base to use, more of a hostel than hotel. The room is basic, clean and has air on. Shared showers/toilets were always clean and tidy.
Due to the centralised location it's quite noisy until around 4am with other guests coming in at all hours.
Mykonos is a very expensive island and this shows in the price of the accommodation for what you actually get. I'd recommend using Mykonos as a stopping point for some of the other islands.
