My husband I will be traveling to Copenhagen for a week long conference mid July. He will be attending a conference at Bella Center. We can obtain fairly discounted lodging at Crowne Plaza Towers. However, in my searches, it seems that this wouldn't be the best spot for exploring, evening dining, etc. If we were to stay more centrally and my husband could have access to public transport within a 5 block walk from lodging to go to Bella Center, what boundaries should we consider? Is Tivoli Gardens considered central? We'd prefer a boutique hotel or lodging with character - not a large spartan site. Please advise so that I can better narrow down our choices. Thank you.
