Betahaus is a cafe attached to a popular co-working space in Kreuzberg. It’s a really lovely space with free wifi, and a pretty amazing crowd of itinerant creative types who gather here to meet, collaborate, and check in online.
The coffee is really terrible though. I had a watery and burnt espresso - it tasted like ass. I’m giving Betahaus two stars only because it’s very pleasant place - a great spot to meet people and do some work.
