We stayed for three nights and loved it here. Before and during our stay Colette could not have been more helpful and charming - for example, emails were answered very promptly and when we arrived she spent a lot of time with us explaining maps and giving advice. The staff and driver are fantastic also. The room was lovely and breakfast on the terrace a great way to start the day. The riad is about 20 mins walk from the main square but we came to really enjoy the familiar stroll through the souk. We cannot speak highly enough of this riad.
One warning: we were caught out by the time change on April 29th (in 2013) and arrived an hour late for our taxi back to the airport. I don't remember seeing a clock anywhere in Marrakech or in Imlil where we had been staying so we had missed it completely! Everyone was so polite and hadn't liked to tell us that we had been late for our breakfast, the drive back to Marrakech....!
