I'll start with the good, the staff were very pleasant and helpful.
Now for the rest:
The property felt a bit worn overall. When we arrived the elevator was malfunctioning so we had to carry our luggage to the top floor.
The room was incredibly warm and, as with many hotels in Germany, there was no air conditioning and it took keeping the balcony door open to cool it down. Additionally, the room's furnishings felt a bit shabby, and there weren't enough power outlets near the bed for us to plug in things such as our phones while also keeping the bedside lamps plugged in. The bed was not at all comfortable.
Perhaps the worst individual thing about the hotel, however, was the hotel's WiFi. It was perhaps the worst out of the different places in Germany we went this trip - the free WiFi was barely useable and limited to three devices that all used the name of the person who reserved the room and the room number to authenticate. My partner and I kept kicking each other off the WiFi because if our phones went to sleep for even a few moments they would disassociate and it appeared the hotel's systems weren't good enough to keep track of if an individual device had just reconnected or if it was a new device entirely.
Finally, the booking image you see is NOT of the hotel itself, but rather of the hotel's restaurant. The hotel itself is adjacent (connected by a long hallway) and is very much of the time it was built (likely sometime in the 1990s).
