We can just recommend this appartment (for two People)!
The communication with the host, the Check-in and Check-out as well as the place itself were simply amazing for our short stay in Thessaloniki! Everything we wanted to visit in the city could be reached by foot. Apart from all of that, the small flat was super clean and tidy, we got towels, shower gel, shampoo, toilettpaper, etc. Last but not least the Appartement also has a nice (quite big) balkony on the 8th floor with a great view over the City.
All in all it could not have been better - thank you Elena & Nikos :)
