The cycladic "units" are a very nice touch, and the top lighting window lets in ample natural light (which is a bit of a problem if trying to sleep early, though).
Rooms are spacious, with ample power sockets, and surprisingly, the in-room safe is fairly secure too (though not bolted down very well).
The breakfast buffet is small, but with a surprising selection of sweet and savory foods. There are various healthy options too, and the number of components available in the buffet means you won't be getting tired of the fare during your stay.
However, the hotel's network uplink is absolutely TERRIBLE - while WiFi signal strength is great, the modem is less so, and the connection keeps cutting out every few minutes. Bring a backup connection if you can.
The locks are okay, but the main door lock started slipping on me, and I had to jiggle the cylinder back into place every few openings. Speaking of doors, the door tolerances are terrible, with huge gaps between the wings. On windy days, expect actual whistling.
Finally, while the units are decently sized, the distribution of space leaves something to be desired, in that it doesn't leave a lot of places to stow baggage - although I was travelling fairly heavy, with large suitcases.
