Alex is a great host, he welcomed us outside the apartment and showing the way inside.
The apartment was clean and is a good choice for those who want an apartment for a short stay near hauptbahnhof and near city center (30 min of easily walking or 3 metro stations away).

Also we forgot 2 pair of winter shoes in the apartment, Alex called back to inform us that he found them and we have shortly met to have them back :)
