I've been visiting Tunisia for almost 14 years, usually staying in Sousse, so it is like a second home to me, and have stayed in many different hotels. I last stayed at the Marhaba Beach in 2007 and my report at the time is on here. There aren't many recent reviews on HT and the latest is pretty dire, but I get the impression that the reviewer didn't really like much about anything in Tunisia. It might be worth having a look at other review sites but always bear in mind that reviews are often subjective so one sometimes needs to read between the lines.
