Rooms are located on top of the hill right above the port. The view is amazing, and spending time in the balcony watching it is a must. Room was really clean, the owners was really polite and there was a mini van to transfer us from/to the port.
Donousa (Stauros) is such a small village-port that everything is really close to rooms. I would recommend it to anyone wanting to have a peacefull and nice time.
I found it a bit expensive for its objective data, but the view was second to none!
