Just returned back from an Oct 21-25 trip from a very friendly riad run by Adil and Badr. These guys make you feel very welcome and have great knowledge of the local areas, showing you around personally in order to help get your bearings. Souks are a 5 min walk and the Square around 15 mins.
The riad is a very serene place where you can escape the chaotic culture outside. We had a lovely 4 poster bed with lounge area and ensuite. The ladies who service the rooms leave them immaculate and even re-fold your clothes onto a clothes horse, should you leave them out. The outside surrounds as with most riads within the medina are juxtaposed with local life which on first sight seems a bit threatening but you soon realise its not the case.
We had an authentically cooked meal in the riad, but the best food by miles is in the square with the local guys who set up sausage and kebab bbqs every night.
The local restaurant that the riad recommended is extremely expensive - a fixed price of around £100 for 2 people vs a typical evening meal price of £20. However the spa that was recommended was amazing.
A wonderful riad for an amazing city
