We traveled with 2 small dogs and the Royal Copenhagen was great place to stay with them. Many people here have dogs. Call ahead, because only certain rooms are allowed to have dogs. Lots of nice grass area around for the dogs.
Good continental breakfast, with danishes (of course), also juice, coffee, tea, oatmeal. Not a full hot breakfast - but plenty of options.
We did not use the pool, but some others did. Was very clean, just not so warm outside.
Room was clean and comfortable, some furnishings were a bit dated, but all seemed clean and functional. Plenty of hot water for showers.
