Nick has a nice spotless clean room, super comfy bed, a nice modern private bathroom with a nice shower cabin. I stayed for 2 nights only so I didn't use the common areas at all, but it seemed nice too! The location is almost perfect, with around 13 minutes walk to the nearest metro station (which has direct links to the airport and all major stations), and plenty of great cafes and bars around.
I will definitely be staying at Nick's next time I'm in Athens...
