Pros: This is a large hotel with beautiful well maintained grounds and beach, all outdoors area is very beautiful. The food was good, plenty of choice and fresh.
Cons: location if you don't have a car is quite remote, close to a fast road with no pavement.
Beds were the biggest nightmare. Very uncomfortable and twin beds pushed together although I requested double, the mattresses kept sliding off the bed frame, mattresses were very soft.
There were loads of ants in the room and bathroom.
Room and bathroom quite basic and a bit dated for a 5 star hotel. No bathrobes. We did stay in another 3 star nearby hotel 1 night and the room, bathroom, toiletries were much better and fresher, there were bathrobes, coffee machine with capsules and very comfortable double bed.
Overall Kassandra Palace is not a bad hotel, but it's not a 5 star hotel. I'd say good 3 star hotel with beautiful gardens, beach, pool area. If you don't expect 5 stars, you will be pleased with this hotel.
