Highly recommend a stay if you're looking for a good-value base for working in/exploring Thessaloniki. Christos is a fantastic host - always available for any questions/suggestions and such a friendly guy. We had some issues with the wifi on the first day and he sorted them out quickly. Check-in was super easy. There are supermarkets and coffee shops nearby. We relied on taxis to go further afield but I believe there's a bus line to the city centre if you need it. No problems!
