On one hand, we loved the hotel for its tasteful decor and central location, on the other hand, there're plenty of room for improvement.

To start with what we like about the Dar:
(1) Central location, (2) stylish decor, (3) Nice rooftop terrace

And what we're not so sure:
(1) No window in the room meaning that we have to keep the door open to let air in. Result: lack of privacy given that our room was on the 1st floor facing the main courtyard with reception area right downstairs. I believe the situation might be better with other rooms not facing the main courtyard.
(2) Arriving late in the evening at Marrakesh, we arranged private transportation from the station with the hotel for 100 Dirham one-way (while taxi costs about 15-30 Dirham depending on your negotiation skill) for added peace of mind. We ended up waiting outside the station at night for half an hour despite calling the hotel up a few times. Every time the answer was that the driver would arrive in a few minutes (without any apologies). When the driver arrived, he even made up excuses that he had been there before our arrival time and that he couldn't see us. But the fact is that we were there all the time and apparently he was just being late (there weren't that many people so impossible to miss especially since he's supposed to be holding our name plate). It might just be the problem of the driver BUT, advice: there're plenty of taxis right outside the station, so NO NEED to arrange transportation service with the hotel.

Lovely belgian host greeted us upon arrival
Very pretty riyad with traditional features
Good breakfast - whenever you want it served
Very laidback and peaceful atmosphere
Nice to have an outdoor space and room on the top floor

Stayed 4 nights during October to celebrate a birthday. We had 2 rooms at the riad in the second of 2 joined buildings. Both rooms were nicely decorated, good bathrooms and had a little outdoor seating area outside our rooms.

Upstairs there is a great roof terrace where a great and varied breakfast is served. We also enjoyed a great dinner there one night.

All the staff and hosts were very friendly, helpful and hospitable. They were great at answering all our questions, suggesting places to go/things to do/restaurants/organising airport pick up and drop off etc.

The Riad is located in the Bab Doukkala area, NW of the big square within the medina, but it is an easy and interesting walk to the souqs, square etc. and we much preferred to be in a quiet more residential area. The nearby food souq felt much more authentic than the tourist souqs and was an interesting morning stroll, but mind the motorbikes!
You can also walk to the new city and the Jardin Majorelle as well.

We really enjoyed our stay there and would recommend the riad and happily return too.

Set in the back street tranquility yet less then a minute walk from the true hustle and bustle of Morrocan city culture. We were waited on superbly by Robert and his staff (you must go)
