Not worth it.
After staying in a different, lower rate and cheaper establishment in Dubuque last time we visited, we thought we'd try a this beautiful old hotel. We regretted it. Check-in was very disappointing: not only was our room nor ready at check-in due to a "system" issue (everyone else in line had a room ready), but the response of the staff was less than accommodating: we were told to come back in 15-20 minutes, which we did, to wait in line again, to be told the same thing again. After waiting in line three times for 45 minutes, we were finally able to check-in. After expressing disappointment, I was told they'd make a note for the manager about the issue. I've heard nothing.
Our room was on the 5th floor, street side, and the bass from a nearby bar kept us up till bar time.
Overall negative experience and would not recommend.
