First of all, great location. Especially if you're coming from the ferry. 5 minute bus to Mykonos Town, and then a 2 minute walk from the bus stop. Beautiful street, right in the heart of the city.
This place is very bare bones, no frills. So if you're looking to save some cash and don't need tons of amenities and extra pillows, this is for you.
The negative: The actual room that the toilet is in is the shower. Not a huge deal except the floor drain is just open and uncovered. There is standing water in it and a cockroach came out. I understand this is a reality of old city living, but I was disappointed in the owners response. The manager intermediate person basically just said no one was around to help or spray and they were sorry.
They should at least put a drain cover on that floor drain, or provide a plug that can be used when the shower isn't running to keep out the bugs.
