The LOCATION is in the best corner of the Dam square, which itself is in my opinion the best location in Amsterdam for pedestrians. Across from the 5-star Hotel Krasnapolski, which is excellent in every way. Rho is close to many popular restaurants, bars, canals, with short bridge to the red light district.
That said, the rooms are extremely efficient, small, and therefore more noise than a larger hotel. The bed I slept in was one of the most comfortable ever, but just for one.
