Does anyone know of any unique hotels that I should book for Denmark? Open to large hotels or small boutique ones so long as there's something special about them like good views or awesome decor :)
Look into Nimb Hotel. It's a high end, beautifully furnished hotel which overlooks Tivoli and is across the street from the train station. They only have 13 rooms and all of them are unique. There's a great bar on the 2nd level with a roaring fire in an enormous stone fireplace and shishi couches all around which are perfect for business meetings or a drink with the wife. Great brasserie downstairs too with views of Tivoli as well.
I also like the Axel Hotel Guldsmeden. If you're staying with other people, I suggest you get the penthouse suite. Totally amazing and has it's own private rooftop deck (and huge puffy lounge seat for two, with a fire pit if it's cold) with a great view of the city. They also have a great scandinavian spa on site. Love the ambiance of this place.
Avenue Hotel is another great boutique hotel. This place is just delightful, but if you're looking for a place that's almost hostel cheap, check out Hotel Wakeup Copenhagen. It's so cheap for Denmark and very clean. Free wifi down in the huge lobby lounge area too.

Kim has some great recommendations above, in Copenhagen I would add Hotel D'Angleterre, its an old historic place with an incredible location, but it is extremely expensive. It just went through a long renovation and while some people feel it is too modern for a historic hotel, I've heard very good things about it (I haven't been since the renovation).
If you want to get outside of Copenhagen and explore some other places on overnight or multi-night trips, I absolutely love Falsled Kro (http://www.falsledkro.dk/uk_safari.html), it is an extremely charming inn out in the country on the island of Funen (about 2 hours drive from Copenhagen), with one of Denmark's best restaurants. An extremely memorable place where they make sure every little detail is perfect. Rooms are great, staff is attentive, restaurant uses ingredients from their own garden and surrounding farms, raise their own quails, etc. A very hyggely place. You can drive here from Copenhagen in 2 hours for a quick stay, but I like to combine it with a trip to Ribe and/or Ærøskøbing, which are both very charming places to visit.
Ribe is one of my favorite places in Denmark. It is Denmark's oldest town and extremely charming. One night is enough here as it is a small place, but you could spend more if you really want to enjoy the old houses, the cathedral, and cobblestoned streets & alleys. Hotel Dagmar is a very old, historic hotel that sits on the town square right across from the impressive cathedral. I'd say the rooms are average, but the hotel is very historic and charming and the location is a 10 (Torvet 1, Ribe 6760, Denmark). Right next door on the town square is Weiss Stue (Address: Torvet 2, Ribe 6760, Denmark). If you want unique, Weis Stue is it - built in the early 1600s, its probably one of the oldest continuously operating hotels in Denmark or the world. Rooms are tiny and the entire place is old, but it has amazing character (from the outside, its half timbers are slanted from years of shifting and inside there is a great old restaurant, that you pass through to get to the ladder that leads to the rooms upstairs). We stayed here in the hearf of winter one time and it was a great, unique experience. A nice B&B in Ribe is Den Gamle Købmandsgaard (HundeGade 25, Ribe 6760, Denmark). If you make it to Ribe, there is a nightly walking tour with the Night Watchmen that takes you around and shows you the city. Definitely do that, but set aside time to wander the little streets and alleys. Very neat place.
If you make it to Arhus (a very cool city & university town), V Villa Provence is a great boutique hotel in a good location (http://www.villaprovence.dk/hotel-aarhus/location.aspx).
Closer to Copenhagen (about an hour north, near the town of Tisvildeleje), is Helenekilde Badehotel (http://www.helenekilde.com/site/en/index.php - Strandvejen 25, 3220 Tisvildeleje, Denmark). An extremely charming hotel that sits on a bluff overlooking the sea. Understated, casual luxury. This place has a great vibe and overall feel. In the summer they do something they call "Summersessions" and "Musicsessions" with dinner and live music (probably need to book in advance). This is very unique and charming hotel and is a very nice place to stay, especially if you want to have a nice meal, lounge on the beach or would be interesting in taking walks and bike-rides through the forest/by the water, etc. The town of Tisvildeleje is very charming with a great beach (an easy walk or bike ride from the hotel) and a little further on, Liseleje is also a nice little beach town (reachable by a bike ride through a forested area along the water or by car).
One of my favorite little Danish fishing villages is Gilleleje. Within easy reach of Copenhagen (by train or car), Gilleleje is extremely quaint with a great litlte harbor where you can go down and eat fresh fish and drink beer with the Danes. Just on the outskirts of Gilleleje (but an easy bike ride or walk into town) is the G Gilleleje Badehotel (http://www.gillelejebadehotel.dk/hotellet/?lang=en - Hulsøvej 15, 3250 Gilleleje, Denmark). Nice setting with beautiful views where you can walk or ride down a little path to the fishing village and harbour.
All of these places definitely qualify as unique in their own way. Hope that helps.
