The Hotel Kaiserhof was a clean, safe place to spend the night, but was nothing special. The TV had a very low volume, even when maxed out. The room was very hot and so it was difficult to get our child to sleep, but that is to be expected as it is Germany in late spring and A/C is not necessarily common. It is a short subway ride from Frankfurt City Center. The neighborhood in which the hotel is located is a bit rough around the edges, but seemed safe enough. The staff was helpful and friendly and the breakfast was very good in the morning. They do have parking just across the street for 8 euro, but there is a very narrow tunnel you have to drive through and it was difficult to get even a small car to the parking area. Definitely do not plan on using their parking if you drive a large vehicle. Overall, I would not stay there again, but it is ok if you just want a place to rest for the evening.
