The location of the apartment was great, quite central and well connected. However, this is definitelly an apartment for short term stay only. As we were staying in the apartment for more than a month and we were on a business trip it was especially important to us to have a good internet connection. Unfortunately we lost internet connection the first week and we had to use the one from the other floors which was very very poor, almost non existent. We asked the owner to check what is happening, he said that he asked the internet company already but the connection was never fixed during our entire stay.
Moreover, we were not able to cook in the apatment since the electric stove was not working. This was also adressed but never fixed and constantly ignored by the owner. It is not fair stating that you offer a kitchen which is not functioning. After all the apartment was not cheap at all.
Finally, since we were 2 people staying at the apartment we needed two sets of keys. We were requested to pay 50 euros deposit in cash in order to receive the other key. We were told that the money will be returned to us when checked out. When that moment came the owner told us that they will need 2 weeks to return the money on our bank account and not in cash since they went on a holiday.
Overall, not so pleasant stay in Germany!
