Hans is an excellent host. Unlike other stays, we had the opportunity to meet Hans personally. He welcomed us at the house and even offered to pick us up at the subway station. Arriving at the house we had an interesting conversation about Germany, which gave us an insight from someone who lives there. This was very nourishing for us to learn more about the country we were visiting. When we left, Hans kindly drove us to the subway.
For all the above, Hans is a very friendly, sociable person and makes you feel very comfortable.
About the material conditions of the room, everything was very good: the bed was comfortable, the room was spacious and clean. The bathroom as well. The kitchen had all the amenities. It also had a very nice terrace that we could not enjoy because the days were short, but I am sure it is a very good place to spend a nice time during a summer afternoon.
The only observation is the location. The nearest subway from the house is about a 15 minute walk. Then, from that station, the center of Berlin is a reasonable 20 minutes away. But this is just a detail in relation to how good the whole stay was.
