The flat was perfect for my stay in Berlin, and Frank was a great host—responsive and quick to answer any questions. He was able to accommodate my last minute booking, and checking in and out was incredibly uncomplicated, which was perfect for my tight schedule. The flat is exactly as represented! I wasn't around much to take advantage of the amenities, but the kitchen seemed like a great place to have some meals and hang out. One thing to note is that the internet wifi was pretty slow/unreliable for me, so don't expect to get much work done, but that really shouldn't be much of a problem for most people and in the end was fine for me as well. I would happily stay in Frank's place again and would recommend the flat to my friends!
