Stayed here for 9 days earlier this year. Patrick, his friends and family go above and beyond to make you feel welcome and your stay enjoyable. As other reviewers have said, it is an oasis of calm once you walk through the entrance.
The rooms are quiet (once the other guests have settled down) and dark - perfect for sleeping. Bathrooms are large. Everything is clean and attractively designed.
The common rooms are stylish, yet cosy. Breakfasts are huge and included in the price of the room. You can also have a fabulous, home cooked dinner in the riad.
It is a little hard to find, but it is in a quiet area of the Medina and close to everything.
Patrick can send some one to bring you there. However, patient, adventurous types can try to find it themselves - best attempted if you had a short flight and plenty of sleep. ;)
