Uncomplicated, safe, quiet and no-frills here in a very central location for everything in Thessaloniki.
Very good price for the location and I am told by locals that these apartments are used often by natives for work trips and family visits, which shows they are reliable and good value.
Perhaps 'luxury' is a slight exaggeration, but the place is not exactly spartan either. Shower, Wi-Fi, aircon (and heating, which worked well), fridge and TV all fine. Comfortable bed, satisfactory level of cleanliness, enough space, and straightforward check-in and out process. My apartment had no kettle or microwave (but an electric hob and oven), but for my short stay not an issue - and the building is in the midst of restaurants and takeaways so there are plenty of options. Not a sea view or cityscape either, but certainly a private feeling, and the area and the building felt very safe at all times of day and night.
Won't hesitate to book again at that price. All good.
