The popular cafe Daen's Cafe next door was completely full, so I ended up here instead. During the afternoon on a weekday it was pretty much empty. The staff was friendly, and said it was fine to use laptops. Plenty of seats, very fast wifi, power outlets. There's no "menu", but they have tea, coffee, and pressed sandwiches (which were tasty). The vibe is a little unclear though, it feels like a mix between a cafe, pub, bar, and restaurant. Anyways, it was a solid place to sit and get some work done.
Copenhagen is still a great city for cafe and coworking. There are plenty of laptop friendly cafes, good for working or studying. I recently found Cafe Fiol, a small cozy cafe just by Nørreport station. It was very quiet on a weekday, plenty of seats, power outlets, and wifi (although a little slow).
A super cozy cafe near in Zhongshan. Lighting, design and music feels very cozy. There are two larger worktables in the back, good for working. Note that there is a 2 hour time limit, although it's only enforced if the cafe is full. We stayed for around 3-4 hours without getting kicked out.
One of my new favorite spots to work in Shibuya, offering cool vibes and good natural light. The cafe is located in the "sequence" hotel at the new MIYASHITA PARK mall. It's on the 4th floor just next to the hotel reception area.
The space is large and comfortable for working, with many seats and several large work tables. It's a popular spot though, so you'll want to arrive at a good time to make sure you get a good seat. Mornings are definitely the best time. It was very full in the early afternoon, but started to clear out around 6-7pm. The large worktables have easy access to power outlets, and there's WiFi (it works, but definitely a bit slow).
The cafe has a large selection of food/snacks, and a decent selection of drinks (the tea selection is quite small though).
Korean style cafe serving shaved ice and playing k-pop music. It's a little hectic, but the 2nd floor window seats are great for working, especially in the morning when it's a little quieter, or if you put on your noise-cancelling headphones. The cafe wifi is a little slow, but you can use the Shinjuku Free WiFi instead, which was much faster. The menu does mention a 90-minute time limit, but it doesn't seem to be enforced (at least not on a weekdays).
Great for early morning work since the Starbucks opens much earlier than the rest of the LUMINE EST department store in Shinjuku. It was basically empty until around 10am. There's very fast WiFi thanks to the free Shinjuku WiFi. No power outlets though. To access the Starbucks before the department store opens you have to use the escalator available from the road side outside entrance (the underground entrances from within the station are closed).
