The apartment is just like in the pictures, modern, spacious and well equipped. It's perfectly located, very close to the White Tower, with many bars and restaurants within 5 minutes walk, in a quiet but safe side street.
There is even a gym just a couple of minutes up the street.
I stayed just for one night in early October 2019, and Nick was kind enough to meet me on arrival and was there also when I left. He was also very responsive to my queries and recommended to take the X1 bus to and from the airport, cost 2 Euros each way, and about half an hour to/from Kamara bus stop, which is only 6 minutes walk from the apartment. Great!
Highly recommended, and I would stay again when back in Thessaloniki. Thank you Nick!
