Stayed here for 5 nights. Excellent location, literally 2 minutes from Jemaa el Fna. Hard to find the first time - turn left just before second overhead stop sign on Dar Zitoun (if heading away from Jemaa el Fna), failing that ask someone but be prepared to pay for their assitance.
The hotel itself is simple but very pretty. The rooms are basic but have everything you need, as with the bathroom. I imagine the rooms are good in summer as they were very cool.
There is a courtyard with seating and an excellent little roof terrace to relax on in the day or night with a table, chairs and cushions.
Breakfast is provided in the morning which we were not expecting and the staff are very welcoming and helpful but generally leave you to get on with it.
The manager Fouad was kind and relaxed and didn't seem bothered when we arrived home pretty late a couple of nights.
We went to a couple of other Riads of friends we met, and Riad Zitoun definately seemed the nicest.
