"Wifi is fast enough and there is enough space for me to comfortable work. Besides the Airfy Free Wifi there is also a Vodafone Hotspot / Free WiFi and Homespot that I haven't tried yet. (I do have Vodafone but not from Germany so not sure if that would work?) I've seen one table with two power outlets, there may be a few more. It's moderately noisy, but even during lunch rush hour I was able to work here. It's now almost 3PM and there are only a few people left. They have good coffee, breakfast, lunch, pastries, etc."
