Experience: The staff at the Riad are incredibly accommodating. Adil went above and beyond to help with any request, and communicated with taxi drivers on our behalf (we had a very limited command of either French or Arabic).
Amenities: Having WiFi and free breakfast is a big win, especially when you get good coffee and a selection of teas. Other amenities such as free bottled water, hot water and dependable heating /cooling unit are also a huge plus.
I would advise communicating with the Riad, right after you book, so you know what room you'll be getting. The details may differ from what you see on the Hotels.com site (# of beds, size, layout, etc).
Bathrooms are on the smaller aside but adequate and clean (make sure to have slippers with a good tread, so as not to slip coming in and out of the shower).
Location: We quite enjoyed the peace and quiet of not being in / right by the medina.
Other: Riad l'Escale was a great place to stay while experiencing Marrakech. We got to meet the owner who was very warm and welcoming, and hosted a lovely New Year's Eve party right in the Riad. I would definitely stay here again, if I'm back in the area.
