Quiet neighborhood, almost secluded. Far away from nightlife, but the point was sleeping, not partying. I arrived for a late checkin (11 PM), staff was friendly and was able to recommend something for the few hours I was in Frankfurt. Clean room, clean neighborhood.
I loved the fact that breakfast was included, and the fridge was stocked with water, juice and beer, all free. I *hate* being nickel-n-dimed to death by hotels, where you run up some absurd tab by simply eating bagels and cream-cheese. This was a refreshing change from that.
