Thomas's brother Nektar was very friendly and responsive. He answered all my questions about the apartment and Thessaloniki. Overall, they do a great job of hosting! We especially loved all the public spaces of the town--the markets, the waterfront, all the Roman ruins. Our favorite night out was at Anatolia, a restaurant 1.5 blocks away (left out the door, then one left on the first street. On the right is an antique shop at the end of the block; next to it is Anatolia.) We enjoyed their tasty local food, very inexpensive, and paid only $3 for the 10:00 pm performance of the most amazing local music we've ever heard, truly talented signers and musicians.
