Henning's place is amazing! It's extremely relaxing and peaceful inside, and we highly recommend staying with him. The location is spectacular, in a very nice neighborhood in Berlin, and about 10 minutes walk from the S-bahn which goes directly downtown to the Brandenberg gate station, allowing easy access to tourist sites. It's also about a 25 minute walk to the Berlin Free University, and to other S-bahn and U-bahn stations, making it a great choice. It's also only a short cab ride to Tegel Airport. The only problems we experienced were with the internet, which we found to be slow and difficult to connect to (hopefully can be fixed, and worked enough for us to get by as it was). Thanks again Henning for being a great host!
