9.6/10 Exceptional! (118 reviews)
This is a lovely hotel with equally lovely staff. It has a variety of charming sitting areas where you can have breakfast, dinner or just sit, drink and relax. Little more than a minute from an outstanding beach with a few other bars, restaurants etc. Not the usual Greek resort but it very quickly grows on you. The hotel restaurant’s menu looks at first glance, nice but not eye- catching. Oh my lord though, don’t judge that book by its cover. I had the greatest moussaka of all time - like no other. I might never order it again because it would never be as good. And the kebabs were pretty otherworldly too. Came away happy and very relaxed. Thank you all.

8.4/10 Very Good! (84 reviews)
Great family resort the pool and location of the beach was wonderful. Kids enjoyed free ice-cream and popcorn throughout the day. Pool service was pricey but there are many options very close by for food and drinks. Our room (family) was quite dated however we knew people in a single room and it was newly renovated and had great views.
