This used to be Steigenberger Esplanade and they were top notch in all areas which is why I booked my stay here again for the umpteenth time. We stayed for 2 nights in a beautiful suite overlooking the city center of Jena on the 7th floor. The restaurant staff, which was still Steigenberger staff, is amazing, attentive, polite, and kind. However, the new staff needs training on customer service.The first night we were there the hotel had a fire drill (necessary i get it.) However, there was not one Dorint employee anywhere to tell us where to go. I was there with my mom who is 86 who just had hip replacement surgery. In the amount of time that it took my mom and i to descend the seven flights of stairs, trying to find our way out if there had been a real fire, we would never had made it out. Still no Dorint employee in sight! I must mention that there was a whole family that joined us on our journey to find the escape route so it wasn't just my mom and I that were having these issues. When we finally saw a Dorint employee, he told us we needed to climb all the stairs back up to the seventh floor although the elevators were functioning again! (We took the elevator.) The next morning we had to get up in time for the breakfast buffet. There was no apology for the terrible nights rest. The room was never cleaned although we requested it be cleaned. When we talked to the front desk about this he couldn't have cared less. Nothing was done by Dorint except collect payment.
