My partner and I stayed here for two nights, and absolutely loved it. It indeed is a perfect retreat, so peaceful and quiet. The courtyard and the rose petals were beautiful, especially during the evening. We booked through booking.com, and were emailed by Rachid a few days before arrival offering pick up services - as we were coming from the train station we didn't need any but he provided us with very good directions. On arrival we were welcomed with tea and excellent hospitality, answering any questions we had and providing us with a map and the best things to see. The raid is a little difficult to find on arrival (ask a small boy and give him 10-20 dirams), but once you find it the first time its quite easy. It is down a very small alley, but it is quite well lit and it didn't feel threatening and a 15 minute walk to the main square. Breakfast was ok, basically bread/croissants and coffee. As some people commented, the two rooms on the ground floor (Secrets du Desert and Délice D'épices) do lack a little in privacy, as guests take breakfast in the courtyard, but it wasn't really a problem for us.
We decided to stay an additional 2 nights in Marrakech, but unfortunately they were fully booked. They transferred us instead to Riad Dar Saba 2, which was also very nice, but lacked a little the warmth and romance of Riad Dar Saba 1 (very comfy beds though!).
I would definitely recommend this riad, and is excellent value for money.
