My girlfriend and I have been 3 nights in this very nice riad. Right in the middle of the chaotic souk, this is like a small oasis of peace and relaxing atmosphere. Service is very good and all personnel very kind and helpful (I would like to mention Omar in particular.. super nice guy and always available to pick us up when lost in the middle of the souk!).
Location can be bit difficult for first comers to Marrakesh though.. it is only 8/10min walk from the main square.. but when you are not used to walk through the narrow streets of the souk.. this can be quite unconfortable especially when it gets dark
