Christos is honestly the best host anyone could ask for. He was very accomodating and really took care of my requests and needs for my long term stay in Thessaloniki. The apartment is very modern and fully equipped with everything you will need and more. The fast Internet and desk set up are perfect for someone who works from home, although the neighbour's dogs can get a bit loud during the day. But if you're out most of the day exploring the city, that shouldn't be a problem. The apartment is located in the Upper part of town and is close to supermarkets and fruit stands. It's a 20min walk to the city centre which isn't too bad. I would highly recommend Christos' apartment, both for long and short term stays.
