Fantastic hotel. Located in the CBD opposite to the train station. My room was clean and had everything I needed. Everything was new and hi tech. Staff were very helpful (I asked about the laundary room and the guy at the reception simply took the elevator with me and walked me to it). Just a great hotel. Will be coming back.
