I have stayed there many times! It's a quiet area and no one is bothering you. You don't get sheets to cover yourself and the bed is really hard (even my Ghanaian boyfriend reckons that). If you sleep on your back or tummy it's alright, I guess.
Self contained rooms for only 20 GHC (10 USD).
Stanbic and Barclays banks are around the corner. It's next to another hotel (which is very expensive) and the Burkina Faso embassy. But to find proper food (like rice) you have to walk for a while.
By the way.. another friend of mine told me about some huge ants walking inside his room. More guests told me that, but they didn't complain about it.
It's possible to rent a room for a longer time, but maybe those are already given out. Last time I was there more than 3 people were renting for a longer time.More
