I stayed in Athanasios apartment for 4 days with some friends. He was very easy reachable for Check-in and very helpful with some tips for the city.
The apartment is a bit outside the city center, but reachable by bus or taxi (or a 30 minutes walk). The balkony and it's view over the city is just amazing, whereas the rooms (especially the bathroom) are a little outdated. Nevertheless I would recommend a stay :)
