Our group of 16 booked the entire Riad for 5 nights in May. We found Gabi and Pierre to be delightful hosts who went out of their way to make our visit a positive one. (I'm sure they would have been a bit shocked/stunned by this loud group of Aussies hijacking their Riad!)
Gabi & Pierre have only recently taken over this Riad, and they were busily making small improvements to the décor whilst we were there, ie. painting etc. Very nice people.
As mentioned previously, the location is very close to Djema El Fna square, which was part of our reason for choosing it. Even though it's in the middle of the 'action', we heard no noise from outside at any time night or day. A very peaceful Riad.
The only negative in our experience here was that the ground floor rooms are humid with a slight musty smell and have no air con. We had no option but to utilise all rooms with our group, however if you have the choice I would recommend you ask for an upstairs room. The hosts arranged free standing fans for us when they could see how unhappy we were about the lack of air con, which was much appreciated. I'm not sure how they can fix this issue, but it needs to be attended to.
Also previously mentioned is the mosque right next door. It is definitely very loud, very early. We weren't concerned about this though as most of the group had not heard the call to prayer before, so it was a bit novel to us (no disrespect intended).
Gabi and Pierre provided a 'last night' dinner for the group on the terrace, and it was absolutely delicious. We had 'tangine' (as opposed to tajine) and salads - the whole group agreed it was the best meal we'd had during our trip to Morocco. I recommend it!
