Pullman properties in Liverpool

I have stayed at The Pullman before and had no issues, however this time we were not overly impressed. I paid for a king room, but when it came to the evening we soon discovered we had been placed in a room with a zip lock bed which had not been connected, causing there to be an uncomfortable and noticeable gap between the 2 singles. There was also dried blood on the sheets. We spoke to reception and we were offered an alternative room with a king sized bed. Unfortunately, the room we were placed in was directly above the arena where a rave was taking place meaning the bass reverberated around the whole room until approx 11pm. We had been out for a meal on the docks, and upon returning to the hotel we were met with rave goers slumped in the doorway, and a guy urinating outside one of the entrances, as well as groups fighting directly outside and gathering in the hotel bar/foyer. Not a great experience at all!
