I really loved Stockholm and preferred it over Copenhagen. It was a bigger city, more metropolitan with better shopping. The drawback to going during the winter is that the sun starts setting at 3pm so you lose a lot of daylight. It was also snowing and very cold when I was there making walking around a bit dangerous at night when the sidewalks froze over.
Nonetheless, if you end up going to Stockholm, here are some the things you must eat, see, and shop.
One of my favorite meals here. Just simple and hearty food. We got a few Swedish classics like the potato pancakes with some other just general classics like steak. I thought prices were very reasonable - for 2 starters, 2 entrees, 2 drinks it came out to $50pp.
The more casual sister restaurant of Oaxen Krog and definitely more experimental than Rolfs Kok. By experimental I mean that they have things like topside of elk or deer shank or celeriac (a root) and other things I hadn't really tried before. It's highly rated with a rustic interior and probably great views during sunlight since it sits near the water.
Prices here were also reasonable with 2 starters, 2 entrees, and 2 drinks at around $50pp as well.
This is a great seafood focused restaurant located in the Ostermalm Saluhall Market. Fresh fish, shrimp, mussels, etc, in a simple, clean style. I opted for the Toast Skagen (shrimp toast) and salmon tartare. When you're strolling through Ostermalm and getting hungry, definitely duck into the Saluhall and look for Lisa Elmqvist for lunch.
Fika is a Swedish custom where they take a coffee break with something sweet. After lunch at the Meatball shop we went for a fika at Il Caffe. It's like being transported back to Williamsburg, NY with its hipster/alternative vibe and loads of people working on their Mac laptops.
When you're in Sweden why not try an iconic part of their cuisine - the Swedish meatball. Meatball for the People is located in the hip/ster area of Sofo and true to the neighborhood vibe it is a super casual but cozy and hipster-y restaurant; some elements are self-serve like water and pickled veggies. When you want a great lunch spot while you're exploring Sofo, definitely check out Meatball for the People.
Nobis Hotel Bar
This design hotel has two bars but the lounge was my favorite. Spacious with huge ceilings, it's comfortable and casual and a great place to stop by for a drink.
This is the old town of Stockholm with cobblestone sidewalks, cute shops, color blocked walls. It's very touristy but a must-see to get a feel of the quaintness of Stockholm. While you wander around you can stop by the Nobel Museum and Mårten Trotzigs gränd (alley) which is the narrowest alley in Gamla Stan at 35" wide.
Sofo (South of Folkungagatan)/Sodermalm
Sofo - The new hipster neighborhood of Stockholm, it's not unlike the LES of NYC. There's a strong alternative creative community and some cool off-the-cuff shops.
Sodermalm - We didn't get to explore that much in Sodermalm and instead opted to check out Sofo within Sodermalm but did make time for the photography museum, Fotografiska (see below).
This is one of the main shopping areas with most of the big luxury brand names out there (think: Celine, Louis Vuitton, Chanel, etc) as well as Swedish brands like Cos, Acne Studios, Byredo. This is a great area to hang out and also to stay since the location is pretty central to the city.
If you're looking for Scandinavian interior design inspiration, definitely walk around Ostermalm. There are so many cute boutiques with great furniture, interior design touches, textiles, accessories, etc, that it's a must-see when you're in Stockholm.
In addition to these areas, here are some key things to do:
If you like modern and contemporary art, this is a great place to check out. Two tips: 1) A lot of the museum is free and unless there is a special exhibition that you really want to see, I would check out the free areas first and then decide if you want to pay for entrance into the special exhibits 2) Moderna Museet is located on a small island very close to Gamla Stan and there is a ferry that goes back and forth making it easy to hit up both areas right after each other.
Really awesome photography museum with some impressive pieces by Anton Corbijn while we were there. The photography exhibits were also mixed in with multimedia and sculpture by other artists as well.
Stockholm Public Library
I don't usually go to libraries but this library is so "Instagrammy" because of it's beautiful interior that it's worth a quick stop for a photo.
