I found out about Tunisian hotel policy for non-marries couples the hard way. The staff were kind, and polite enough and tried to assist, but this meant buying another room (meant for groups) for my GF of 5 years.
Take note unmarried travellers, this is not the place for you.
For solo travellers on a budget this is a good spot But the place is spartan. Very, very little to no amenities, basic beds, and AC that is intermittent because it's unable to be adjusted.
The area is downtown and very close to the market, which is good. I didn't feel unsafe, but this area was not particularly well kept. My GF and I both noted that the inner city seemed more conservative than the coastal areas, and there were a lot more judgemental or lecherous looks in this area of town for non traditional dress.
Not "bad", but expectations need to be managed.
Only budget solo male travelers recommend.
