H20's space is right in the red light district of shunjiku. If you're looking to be in that area it is a good location about 10 min away from shinjiku station. The place says it is a none smoking room but it smells like an ashtray. Other than that it seemed pretty clean. I didnt expect a whole lot with the price. Upon check out the front desk was very rude. To be fare I did check out 2 hours late, but that was because i was drugged by the Nigerians in the area. STAY AWAY FROM THE NIGERIANS! Although that was not the hosts fault. Just be careful in the area.
