If you decide to visit Marrakesh, be prepared for extreme heat (in the summer), noise and getting lost in the labyrinth that is the inner city (Medina). While I found this to be an experience well worth having, coming back to the riad after a day of exploring the city felt like heaven. Very calm, with beautiful authentic interior and good rooms with an excellent bathroom. The owner was very helpful, showing us things worth seeing on the map and providing recommendations on where to eat and what to look out for. The staff was also very friendly and the location of the riad is a good one, close to one of the gates of the Medina. I can recommend this place to just about anyone.
Special message for Idriss: the airport is open during the night and you can find a lot of people sleeping on the ground there ;)
