This was the second time that I have stayed at the Leonardo hotel. I found the staff very charming at the reception area. However, I did not feel that the staff in the kitchen/breakfast area were very professional. I wondered if they were new or pratikums learning, which is why I did not complain. Apart from this, I enjoyed my stay at the hotel. The hotel is ideally situated in terms of traveling to the main city area of Karlsruhe. Has lovely decor. However,I wish the bar area could be extended to midnight or even later, as I feel that 11am ia a bit early for closing. Or perhaps you could have the bar opened later on the weekends.
