Thessaloniki--what a pleasant surprise, BOTH times we stayed in town. The first time we stayed at the Minerva in downtown--the center of all the young, hip nightlife. Very fun. The second time we stayed along the coast in the more touristy, yet upscale neighborhood (ie. better restaurants, hotels, etc). In all, we liked Thessaloniki more than Athens and found an awesome place for that authentic Greek Salad. Promise, i will post it here someday.
