I stayed at Hotel Bella Grande during my recent vacation to Copenhagen and had a great experience! The hotel has a beautiful, feminine design, and the service was excellent throughout our stay. The rooms are small, but well laid out and well-appointed (closet space, shelving, a small chair, etc.), so this wasn't an issue for my partner and me. The only thing I would note is that the bathroom is quite small, and the design of the shower makes it near impossible not to "flood" the bathroom! However, this wasn't really a big deal for us during our stay.
We appreciated being so centrally located (very easy to access bikes/metro) during our trip. The hotel also has a restaurant and bar on the first floor, which could not have been more convenient for grabbing a quick bite to eat after long days of sightseeing! I would definitely stay here again.
