A very nice apartment with everything you would expect.
Our only 'issue' was that the bedroom was hot, so we ended up sleeping in the living room, near the air con.
There are supermarkets, restaraunts & cafes nearby, which are very nice. It's a bit of a walk from the waterfront, etc, but we got a taxi, which was only 5 Euros, so it's no problem.
We would definately consider going back if we visit Thessaloniki again!
