9/10 Wonderful! (675 reviews)

Room was clean and the staff were great to us. Hotel’s location was also great. 5 minute walk to the city centre, train, bus station, and Lidl (supermarket). Only thing that could have been better is a little bench for luggage and possibly another chair. We were two people so it would get crammy at times. Also, the walls are thin. Everything can be heard from the hallway. Luckily we had a corner room so it wasn’t bad at all. Overall, we would definitely come to the Dean again!
