The location of this place is excellent if you want access to public transport— just a block from the Hauptbahnhof was great for us.
However, communication with the host was a challenge. Daniel sent a friend to check us in and he was very nice.
There were some issues with the apartment. It felt like it was quickly put together to rent out with cheap items (the pillows were lumpy). The towels hadn’t been pre-washed and left lint everywhere. The TV never worked even though it was replaced while we were there. You use the Internet from the hotel and it is weak and you get kicked off all the time so not good if you need to get work done.
