Abysmal. I have never in my life experienced a holiday like this. Where on earth to start! The fact that everything is dated and not one picture on the website gives a true vision of the room we got is nothing. We walked in the room to remnants of someone's hair removal cream and hair wiped down the side of the shower curtain, dirt rings round the bath and sink, black mould in the air conditioning unit and dust everywhere. Our room was not cleaned once. We had to ask for the bins to be emptied which only happened on days 4 and 6 (bear in mind you can't flush toilet paper here, and there were 4 in our room!). Tea/coffee making facilities never topped up and beds never made. Around the site, toilets were not cleaned, they stank of urine all week. Rubbish was left lying in the grounds and by the pool was a pile of dirty plates that sat there all week! Moving to the restaurant, food was cool, bland, very little choice and one day I had the delight of being served raw chicken. Another highlight was grey leftover peas and carrots with potato wedges served at breakfast. Drinks machines often broken, serving wrong drinks and later we discovered mould and grime in the drip trays. No hot drinks after breakfast, no breakfast teabags. Tables were never cleaned, left grimy and sticky, dirty plates and cutlery and all glass - doors, banisters, handles - had grimy handprints on all week. Never cleaned. The pools closed early, slides were often closed, no sports facilities in a state to be used and no afternoon snacks. Staff were rude, they seem to have given up. The only credit I can give is to the very hard working and enthusiastic entertainment team who really tried to cheer people up. To top it off, on our final day we had a late checkout. A man let himself into our room whilst our son was watching TV , unplugged it and took it away! We were left with absolutely nothing to do for the rest of the day as the pools had been closed off and entertainment crew had finished two days earlier. By far, the worst hotel I have ever had the misfortune to stay in. Such a shame, as Kos itself was beautiful.
