To start with, Marrakech is a very exotic and enjoyable vacation destination: the architecture of the old city is very well preserved and authentic (id you disregard the many tourist shops they are housing), and as such, very photogenic. After our experience in late June, would suggest the following itinerary: 3 nights Marrakech in a Riad in the old city (Like Riad Adriana), 1 night in Imlil at the foot of the the Toekbal mountain, and 1 night in Essaouira on the coast.
About Riad Adriana, a fully concur with most ofnthe previous reviews: it is a lovely Riad in a local, less-touristic neighbourhood of Marrakech. And still very conveniently located. Melanie and her staff have been excellent hosts, helpful with giving all kinds of advice on whatbto do. and where to go. As we also stayed in another Riad, closer to Jema al Fna, I found Adriana to be good value for money. No need to stay too close to the square as after one or two visits you will have had enough of it. Morrocans are very friendly and most of them speak two or three languages, including French and english. It was quite hot though, and if possible, travel in Spring or Fall.
