Staff were polite and attentive. Even with an upgrade, hotel room was dated, chipped tub, rust on faucet, dusty room. Bed was big and comfortable. Common areas are well kept. Restaurants onsite.
Area around hotel was ideal for taking the train/metro. A station directly across from hotel. Lots of dining options, 5min walk to Tivoli.
Hotel is reported as a 4 star hotel even on the local Copenhagen map but did not feel that way.
If you don’t mind a dated room, Imperial Hotel location is ideal for commuting to most tourist spots!
