I found one review from 2007 for you below.

Whereabouts in the resort are these?

Can't remember seeing them/passing them or anything (maybe that was the Raki lol)

Right next door to the Karbel Beach.

I have now added the motel to our reviews here. Hopefully someone can give it its first review

we had a look around these 2 years ago they re stunning all open plan from what i remember. they are a few minutes walk from the beach, but they dont have a pool, or didnt when we looked. we would definatley would have booked if they had a pool but with kids its something we need. but if no pool isnt a problem definatley consider them

Their website, the costs are very good, however, getting a flight there from Newcastle, you wouldn't get much change out of £350 + per person (day flights) for May and therefore it would be cheaper booking a package again.
