Hi,
We stayed in this hotel a couple of years ago.
Nice place built in the shape of a castle and has a lovely court-yard, beautiful marble steps leading up to the pool with a snack bar.
Rooms are a bit on the small side but there were 3 of us so we changed to a family room which was better, very clean and great staff. They had a greek night also karoke when we were there. Kalithea is quite small but try the Kalithea restaurant we had some great nights in there.
Bus stop is just outside the hotel and approx 15 minutes takes you into Rhodes town or a taxi i think is 5 euros.

Hope this helps

Cathy

I have asked for this hotel to be added to our reviews site.
