Absolutely horrendous experience. Nobody was manning reception when we arrived, so a different hotel guest had to phone for staff just so we could check in. The room itself was incredibly small and cramped, but would have been fine if not for the appalling service. When we tried to check out the reception was, again, entirely unstaffed, despite being within the hours it is supposedly manned. Myself and my partner waited at least 20 minutes for someone to come and check us out, and called the provided number multiple times over that period to try to speak to literally any member of staff. We could not get in touch, so had to just leave our key on a small shelf. This also meant we were unable to store our baggage anywhere, which meant we couldn't do half of the activities that were planned. When I contacted Comfotel GRN to complain, they offered no kind of compensation, and had the nerve to even suggest we try visiting again some other time. Spend your money literally anywhere else - these people don't care about you.
