I was surprised to read Elaines's comments. We have recently returned from Mythos - our 4th visit and have always found the apartments very clean. The cleaners are very friendly and come in every day with linen/towels changed 3 times a week.
Mike the barman is fantastic. He works very hard and always willing to help. The bar can be quiet at times, but after a hard day sunbathing/touring etc, it is good to just chill out and chat to other holidaymakers.
Andreas the owner and Andreas the handyman are always around and we have found them friendly and always happy to help wherever possible.
Katelios is a quiet village and Mythos apartments are excellent for a quiet and relaxing holiday and I would certainly recommend them.
Unfortunately this year I broke my foot in the last week of my holiday and have nothing but praise for Mike the barman and Michael the Olympic rep who made my last few days in Kefalonia as enjoyable as possible. I can also recommend the hospital in Argostoli!!
Saving now for my next holiday at Mythos in 2008...
