Myself and my boyfriend stayed in Karras Apts in May and Sept last year and am heading back this sunday.  Cannot wait to be back there again. Great rooms. Basic but cleaned daily.  Very spacious.  Excellent pool.  Apts are just 1 min off the main road so it is very relaing.    As for Tackie and Sula, what can i say, they run the best poolside bar in Zakynthos
