This was my second time at Ulf & Annette's place and it was as great as the first time. They are both very friendly, welcoming and helpful. The flat is well equipped and ideal for longer stays. It's around 15 minutes' walk from West Kreuz S-bahn station as well so an easy commute into the city. The WiFi worked well. Added since my last stay, the kitchen now also have a toaster :)
