Hi beachcomber,
Shirley has contacted me for info for you on the Frosini Garden Apartments. We have stayed here twice - the apartments are about a 10 min walk from the harbour we found the location good. I can't remember if there was air con as we were there both times at beginning of May and it was freezing in the rooms! They are all marble which would be great in the really hot months. The apartments are really nice, quite roomy and very clean. The only downside was the balconies at the front are all behind the trees so didn't get much sun - again probably a godsend in the heat but not so good when we went! There is a really large pool and plenty of room in the lovely gardens for sunloungers (small cost for these).
We were really pleased with the apartments and wouldn't hesitate to stay there again we thoroughly enjoyed Kassiopi.
Hope this helps and if there is anything else you need to know I will try and help.
Amber
