We stayed at Nick's apartment 2 nights, and it was really great!
The apartment is modern and comfortable. The room was really clean and bathroom as well. There was everything you need - shower cream, shampoo, hairdryer etc. Nick was really good host, he picked us up from metro station, gave a city map, and some recommendation about the Athens. Wifi works really good.
Neighborhood is quite and safe so we had good sleep in a night. And the bed is the most comfortable bed I ever slept, we didn't want to get up from it :)
I really recommend Nick's place, you won't regret!
