This Riad is located at the south end of the medina. The hotel staff was friendly and helpful. All employees spoke french and 2 spoke some english. The rooms were clean and beautifully appointed. Our room had a separate sitting room and a large bathroom. Breakfast was included and entailed various breads, jams, and coffee. Omelettes could be added for an additional fee. Breakfast could be eaten in the lovely garden or on the rooftop. The hotel has a very nice view of the medina. The staff can prepare a traditional morrocan dinner in the garden courtyard upon request (this was expensive and without alcohol).
The location was in the medina (tell cabs Ziat gait) or take a 25 minute brisk walk from new town to get there. A 15 minute walk will get you to Jewish quarter and Blue gate (where most of the sights are). This walk was fine during the day, but uncomfortable at night. There are no sights or restaurants right next to the Riad so expect several long walks or negotiate cabs (should be 15 dirham to/from the train station in new town, but the cabs will quote you 40 and you'll have to negotiate - if you have luggage it's tough to negotiate).
We requested a guide for the medina. Our guide was well-informed, reasonably priced, and spoke perfect english.
The other nice part about Riad Dar Chrifa is that the price quoted is your actual price. There were no extra fees for phone calls, holding luggage, taxes, etc.
