We stayed for two night one before and one after trekking in the Atlas Mountains, the Riad was booked for us, so cant comment on the cost. The location of the Riad is excellent for two reasons, first its only a 2 minute walk from the car park that the taxi drops you off at, second its only a 10 minute walk to the Medina. There are a lot of Riads that are miles away from the nearest taxi drop of point, think about this before you book anywhere and end up paying someone to guide you to your Riad.
I would get the hotel to arrange a taxi from the airport which they will do, the taxi fare is 100 dirhams, they will also take you from the car park to the Riad. They will organise a taxi to the airport when you leave as well. Our taxi ended up being the Riads owner.
All the staff are polite and helpful, they didn't try to sell us tours, they just let us be, which was nice as everyone in Marrakech tries to sell you something. There is free wifi, air con in the rooms, nice terrace, half covered if its to hot. You cant really go wrong with this Riad to be honest.
