I stayed at wegmann's place for 2 nights with my girlfriend.
It's easy to get there by Train and metro. Wegmann told us how to get at the ap and waited us until after midnight to receive us. It was nice!
The room was perfect. Comfortable bed, pretty clean and spacious. The bathroom also was great.
The kitchen works to do everything you need! I used the refrigerator to keep some food and cooked to lunch. It was not a problem at all... We washed our clothes too.
Wegmann lended a hair dryer to my girlfriend.
Wegmann is a nice person. Helped us when we ask for something, always fast by the way.
The neighborhood was great. Lots of little cheap shops, cheap restaurants and two supermarkets (less than 5 minutes walk).
Metro is less than 5 minutes walking too. There's a train station(S-bahn) also that close.
I think the only thing Wegmann could be better is to be more talkative, have some conversation, give tips of the city and neighborhood... may try to have some fun with... It would be nice to keep the hosts more Comfortable and have some different and good experience, not just be a "professional" relation. But it's ok! I don't see it as a negative point... We would like it, but we know that's not everybody that would.
It Should have a key on the room's door too. It will get more privacity.
So, that's all.
We enjoyed the stay and we recommend it to everybody.
If we could, we will come back sometime.
