I've recently come back from SS and stayed at the Thomas Bay. My 2nd time in the resort but stayed at the Athena before.
When you're looking at the hotel if you've got a room on the very right hand side you'll hear the frogs but they may calm down in August. If you're on the other side to those rooms you'll either be looking at the pool or the restaurant which is where we were, on the first floor. We only had the sun in the morning and used our towels over the side to help block the restaurant but the noise wasn't too bad (you may want to close the window on the karaoke night unless you're joining in). The beds were the most comfortable I've had on a Greek holiday and I've being going for years. We were disappointed about the fridge but the water was so cheap in the supermarket we just bought cold bottles each day and if you're inclined to a glass of wine in your room you can buy it from the bar and take it up. The wine was v. good and so was the cost of it and for a Mythos as other resorts have been pricier. What we didn't know before we went was that you could hire beach/pool towels for 2.50 p/week (not sure what they're like).
The one thing we found that wasn't really necessary was that they had Sky news on TV in the restaurant at breakfast and evening meals or the football. The staff were very good and friendly. Some staff and cleaners were surprised when we used our limited Greek (good morning, good evening, thank you etc) which they seemed to appreciate but showed that not many people do it very often. Except for one night I think, they had entertainment every night which we weren't into but can understand why some are. The menu isn't bad for a hotel and for the second week they didn't repeat it exactly which was good.
If you're on the beach we spent most lunches at the Mango Bar, the food and staff were very good. For quite a small and quiet resort in the evenings the few bars that were there were competing who could be the loudest, you're sat in one bar and can hear the music from another two.
I hope I'm not putting you off, everyone's opinions are different especially when it comes to a holiday and you have to take reviews with a pinch of salt. If you have a meal out all the tavernas are good, 2 stars taverna is a typical Greek Taverna with no gimmicks.
Overall it was a good two week holiday, sun, sea, sand and Greek food. Wish I could go back!
