My hybrid frame is 15" and seems fine - I think sometimes I'm in between sizes, my mtn bike was a 17.5 and seemed too big. I'm going to try the adjustment on my saddle(thanks KnottedYet). I can't go before the auction ends and look at the bike. I guess if I win it and it doesn't work out - I can just resell it on Ebay. Thanks girls, I'll keep you posted.
