Plus: Very courteous and helpful staff, very close to metro station, central Athens very close, modern building, beds are not too small, clean, safe deposit box in the room, good value for money
Minus: Room is quite small (just about manageable for two people), the room was slightly smelly (nothing too bad, you'll manage if you open the window occasionally), the immediate neighbourhood is a bit run down (although you can reach a vibrant new restaurant quarter in a 10-15 min walk), breakfast is fine but probably not worth 12 Euros
