Just got back from laganas, perfect holiday. Pretty touristy but at the same time, pretty low key during the day. The beach wasn't too crowded (nor was it empty). A great place to stay.
Cactus was a great place to stay, I have to admit I didn't use the pool or the bar. Why would you when your so near to the beach, or the main street for bars.
Great placement, the minimart next door was handy. The staff were friendly too, when our fridge broke they got it fixed by the next morning (we didn't know till midnight the day before).
Damn Nice cocktails. I wouldn't dare go to a place like that in england, a little to tacky. But in Zante it seemed to work, well worth checking.
