Have stayed at two different hotels and a B and B in Rimouski. Hotel Rimouski is the better hotel but certainly no better thsn average. Room had poor ventilation, very humid (water on window ledges all the time) and temp could not be turned below 20C for sleeping at night. Internet signal was poor and inconsistent since we were in a room on third floor at the far end of the hallway.
If you have to stay in Rimouski, despite these criticisms, this is your best bet.
