We booked this riad Zaouiaa44 in July 2013 for our trip to Morocco in April 2014. We booked for 5 nights and paid a deposit via paypal. IN April 2014, one week before we were due to fly out of the country and 8 days before we were due to stay in Zaoiaa44 I received an email from Sophie the owner saying that she had made a mistake in her booking and we could not stay there for nights - only 3 nights were available. We were gobsmacked to say the least. She offered us 5 nights in her 'other riad" which from the website looked awful with no leafy courtyard. She offered us 2 nights at another riad and then 3 nights in Zaouia44 - we explained that especially with a 10 year old we needed to arrive, unpack and stay for 5 nights.
Her explanation for the mistake was something to do with her booking system - she never explained why we had to move and not the other people - we booked 9 months in advance and paid a deposit!!! She indicated that she had made this type of error before!!
DONT RISK IT! WE had to book somewhere else at the last minute which was not easy. Stay somewhere else - there are plenty of reliable and great riads in Marrakesh!!
