It was the first time for our family in this hotel. It is quite old, this is obvious. If it had some renovation, it would be hard to find many disadvantages to it. In general, as 2 adults and 2 kids (4 and 9) we had a great time in a sea-view 6th floor room, with a large double bed and 2 single separate beds. The room size was enough, bathroom quite large, corridor with a very spaciaous wardrobe. The only bad thing in the room was very old stained and kind of smelly carpet. There is a small empty fridge, balcony screen door, AC (very old system) works even with open balcony, electricity does not need a key.Food at the buffet was just fine, we are not extremely focused on food, kids had enough to choose from, there is a good choice of meat and wonderful fish, theme dinners. Beach area is clean and comfortable enough. Beach at the neighboring Pallini hotel is much better (entrance to the sea has no rocks like Athos' beach, where you need footwear), you won't need special footwear there. We have traveled to quite a few countries with kids and I have to say that this was the best sea experience I have ever had, considering that I am not a fan of beach holidays in general. The water was absolutely clean, transparent, calm, warm and simply amazing all the time, We didn't even want to go to the pool. Not much sealife to see, because the bottom is simple sand. We saw a few fish, a medusa, a crab. Staff were all polite and smily everywhere we went. We were lucky to check in straight upon arrival at 11 am. Reception ladies were helpful with information. The best staff are enterntainment team, especially some girls (i.e. Elena), who jumped, danced, sang, and played literally ALL day long and enterntained the kids at night too. Amazing enthusiasm and endurance! A lot of respect to them. It is worthwhile taking a taxi ride (10 euro) to the ancient Afitos village nearby, very pretty streets, wonderful views, good food, overpriced souvenir shops. Little food shop in Athos palace is good enough, we found that food item prices were the same at the village stores.Overall, we're happy with our vacation. We will try to choose this location in the future, thanks to the sea quality.
