I stayed in Athens for 5 nights and I think selecting New Hotel was one of the best decisions ever. The hotel was centrally located near Syntagma metro station and the shopping district. The hotel was well furnished with contemporary interiors, room was clean and inviting. The hotel staff were friendly and helpful. The breakfast were sumptuous.
The "rooftop lounge" - Art Lounge has a nice evening view of Athens.
If you are in Athens, I would highly recommend New Hotel.
