it's not hard to sell out the stamos mate,it's not that big at all!
The malibu is about 200 yards behind where i live,it's definitely in raki,not kalithies,none of the places you'll see are in kalithies as it's a few KM up in the hills, malibu itself is ok,half decent pool and only a 10 minute walk from bar street but it is what you'd call 'out of town'.
For club18-30 holidays i can't recommend hillside enough,easily THE place for this kind of hol in Faliraki to be honest,it's always been club's main property,it's a bit out of town but they have more or less everything happening there 24/7,a lot of the club18-30 parties and events etc take place there anyway and the owners are the same people that own TGI's,they invented the famous faliraki fishbowls that every other resort now has and also own club studios,which are above TGI's right at the end of bar street opposite maccy d's.
