Just arrived back from Kefalonia yesterday.
Svoronata is a very peaceful resort with a few hotels, apartments and tavernas, set in very scenic countryside with little traffic and close to 3 beautiful, uncrowded beaches (2 sunbeds and an umbrella for 7.5 Euros a day). Hence we liked the location - if you want bright lights, loud music, traffic, lots of bars and lots of other holidaymakers, then don't come here!
It is close to the airport, but a maximum of 5 flights went over in a day and was a welcome distraction rather than a disturbance.
Svoronata has the luxury of being away from it all but a taxi ride to Lassi and Argostoli (10 to 12 Euros each way) should you want a change.
The Blue Horizon is a family run business and all were perfectly pleasant and happy to talk. We tended to only be in the hotel infrequently for food and drink, preferring to eat out anyway. The hotel does food from 8am until late at night for evening meals. Although we never ate in the hotel, the food always looked fresh and tasty and those who did eat in the hotel said it was very good. Breakfast is included, but it is very basic and consisted of bread, butter, jam, marmalade, cheese, ham, hard boiled eggs and tea, coffee and cordial. As long as you don't expect breakfast to mean a full English, then this isn't a problem.
The rooms are fairly small but very clean and of a higher standard than a lot I've seen in Greece. The only downside was that with it being a hotel there were no fridges in the rooms to keep drinks cool (obviously intended to get you down to the bar!).
The hotel itself was very pleasant, clean and fairly modern for Greece.
The tour operator for that hotel was Golden Sun and being an ex-employee of one of the big UK tour operators I can safely say that the service received from them was excellent should you need a rep. I've never needed one, but I saw the rep a couple of times a day around the hotel, talking to customers.
Although a last minute booking, transfers from and to the airport were free (usually £10 to £15 with the big operators) and meals were included on the flights who were with Monarch (usually £10 with the big operators).
Ammes Beach was the best for me - loved seeing those planes so close up!
The sand was clean, the water was incredibly clear, warm and you could walk out for miles without it coming above waist level.
Angela's snack bar on Ammes was the best out of all the beaches we tried - she was always friendly and the food was fresh, tasty and excellent value for money. The view across the bay was great too.
