I stayed at the Schlosshotel last year and it was adequate. I reserved a deluxe room and found the room to be very small. Went back downstairs to the main desk and explained that I reserved a deluxe room and expected a room a little larger. The clerk was very pleasant and moved me to another room that was twice the size, albeit with two single beds. I wasn't going to complain again and decided to stay in the 2nd room. The hotel is directly across the street from the Hauptbahnhof and adjacent to the Tiergarten. Having not been to Karlsruhe since 1986, I was pleasantly surprised to see that not much had changed in the city. Karlsruhe is noted for its "sunny" weather in the summer and the city did not disappoint. I normally stay in 4 or 5 star hotels and this hotel certainly wasn't up to that level nor do they claim to be. All in all, it was an average hotel with minimal amenities.
