The apartment was nice and warm, located in a central location to historical tourist sites, in the Historical East Germany area. The apartment block is very big old block, but inside is comfortable. There are a few restaurants on the ground floor of the apartment block, a supermarket just down the street and some significant monuments on the same block. While I was there, we had construction workers building a new high rise next door.
The host was helpful and responsive, however for me the check-in was outsourced to a local agency. They provided a truly dreadful experience, they were rude and lied, purposely trying to make check-in for me as difficult as possible. It was really bad, which is a shame because everything else was ok.
