My wife and I went to skala last year, and enjoy our evenings trying out the local bars. We were very disappointed with Veto's bar, we found the atmosphere very flat, people just staring at the TV screens with no conversation happening. The drinks seemed over priced too considering the stingy measures. If you miss Veto's out when you go to Skala - don't worry, you won't be missing anything!
We went to Skala last summer with Thomas Cook and stayed in the Ermioni appts, the location was excellent - just off the main street, 5 mins walk from the beach. It was very quiet, very clean and we had no problems at all. The only thing we would recommend is that you hire a fan for the heat if you are going peak season!!!
Oh... and I forgot to say we were on the top floor of the appartment block so we had excellent views of the sea!
We really liked this bar, would recommend it. Friendly, fun and a really good atmosphere - everyone is made to feel very welcome.
