We came here in September. The location is convenient, it is between the port and the old town. You can go by foot to Chora, it is a ~15 mn walk to each side, pretty easy. There is a bus stop in front of the room that goes to the city, the port, and a beach (you can also go there by foot ~20 mn walk). there is a supermarket at ~5mn. The room is nice and simple.
Though, we are in front of a very busy road, and we could hear the traffic inside the room, it was difficult to fall asleep because of that. The road does not have a sidewalk, so it is a bit dangerous, I would not recommend walking there with children.
The bathroom is unpractical : the shower curtain does not cover all the sides, so you will spill water on the toilets every time you shower. The water had a VERY strong smell. We thought at first there was something moldy, but I think it actually was a chlorine smell. In any case, it was not pleasant.
the owner gives a tray with dishes, which is a nice touch, though you do not have things to wash them.
the terrace has a nice view, but with all the noise from the traffic and the strong wind of Mykonos, we did not enjoy it as much as we thought. It is not the owner's fault though.
Overall, I do not think it was worth the price.
