If you are looking for a great location with basic accommodation, then this is it! The cost is very economical. I stayed in a single room for 2 nights. The sites are within walking distance and it is close to everything, markets, souvenirs, food places, etc.
When it comes to cleanliness though I am going to give them maybe just a 6 for now, 7 is pushing it, but I know they are improving and making things better. So if you want a not too bad and cheap place to stay for a few nights then I'd recommend Mansour Hotel. I would stay here if I am in Amman again in the future. It's a pretty cozy place.
Just a side note: it's always a good idea to have a roll of toilet paper with you when traveling in Amman, and the rest of Jordan as well, which I always have with me!
