Here currently on a week long award stay (7 night cert used).
Have been VERY impressed with hotel. Ambassador recognition has been outstanding. Not just comping breakfast daily, which they are not required to do, but front desk and bistro staff remembering my name, greetings as I walk past, remembering preferences at breakfast, etc. Still offered 10 Euro a day credit for on-site bistro as well, which is beyond generous...and i am thus reluctant to use tbh Haha

In what I believe is an "over-sized" standard room, which is what I would expect on a week long award stay. Comfortable, and very roomy, especially for Europe. In what I consider a rare perk these days, an enclosed closet and a decent-sized, dedicated work desk with a nice chair. Awesome.

Original room I was assigned had an issue with the Air Conditioning, which necessitated switching rooms. The staff handled it with great urgency and tact. Goes to show that with the right staff, issues are not made out to tarnish the perception of the stay.

Hotel is situated in what I consider an ideal location. 10 min walk to main train station, and 5 minute walk to closest U-bahn station. Immediate vicinity has good coffee shops, restaurants, cafes, etc. Steps away from a more neighborhood feel area. 10 minute walk thru a park to reach the Rhine. Small grocery store across the street, great for grabbing water and nibbles for the room. Having stayed in the FS Marriott before, I like this location better for a lengthier, leisure stay.

High marks in every regard for the property and staff here.
