It is a very new hotel. The wet and dry bathrooms are separated and you can use the bathroom separately. The style is industrial style. The breakfast is also good and rich. It is very peaceful with a view of the Rhine River. Find a location nearby. 20 euros a night is too expensive.
The hotel is located diagonally opposite the Mainz train station, which is very convenient for catching the train. The authentic German restaurant Zenz is a 100-meter walk away, which is highly recommended. The room has a large city view and can accommodate children with an extra bed. The room has enough space and the facilities are quite complete and standard. The lobby bar and restaurant are well decorated; the breakfast price is not expensive, 19 euros per person, and the variety of dishes is very average among hotels of the same level in Europe, and you can eat enough. The parking lot is in the basement of the next building, not far away. I have not experienced other facilities, so I will not comment on them. What is really amazing is the spiral staircase in the hotel, which is very German in workmanship! Take a bird's-eye view of the wooden stairs during the day, and take a bird's-eye view of the light and shadow at night, which is very good! If you come around Christmas, there will be a small night market in the square in front of the station every night, and you can drink authentic German mulled wine!
The place was clean, and the view next to the Rhine river was nice. However, the workers didn't speak English well, but they managed to assist me. A good stay in general
The hotel was aesthetically pleasing and well-maintained, with good services including breakfast and complimentary snacks. Staff were extremely helpful and polite, and a member of staff was on hand at reception to check me in even though I arrived late in the evening. My room was huge and amazing value, and was set up for me beautifully. The location, while not central in Mainz, was reasonably well-connected to the city centre via public transport -- the bus stop was a ten-minute walk downhill from the hotel through very pretty neighbourhoods with regional charm.
