TL;DR: Fast good internet, though can be unstable in afternoon. Many sockets, but not on every table. Often very crowded and the music is sometimes too loud.

One of the most popular co-working spots in the city, but a bit unusual that it has a cafe on the ground floor that is open to everyone in addition to the members only areas on the upper floors. The have a wide variety of beverages and also serve food at lunch times.

Good place to work and they never seem to mind how long you stay. The music, both genre and volume, is controlled by whoever is working so it’s a bit hit and miss.
