The staff in the restaurant was very kind, nothing to say about the service. the food was good, though need to cue quite often. The location is OK, the room was clean.
I don't think that the hotel deserves 5 stars, too expensive for what it is. the admin promised a sea view room upgrade for our honeymoon stay, which was not provided. The gym and the susnbeds on the beach are for extra fee!!!! Never saw it in a proper 5 star hotel. the beds in the room are on rollers that at a small movement the bed moves around at night. We kindly asked to change or to fix it, nothing was done for it either.
My advice, spend your money for something better than Mitsis. Will never go back again.
