Arrived late at night, around 21:00, took a taxi from the airport but the driver didn't know the address. Managed to get us quite close but had to ask a young lad the way and unloaded us at the end of an alley - luckily 2 more youths showed us the way (for a fee!), because it is well-hidden and involves a few turns.
The manager greeted us and showed us the hotel, I got the feeling he is very proud. The hotel is boutique, only 4 or 5 rooms. Ours was quite small but adequate. It was comfortable, although there was only a bathtub with a shower attachment and no curtain which made showering difficult.
A word of advice - wear earplugs. The call to prayer in the morning is very loud, and occurs at around 04:45!
Breakfast was served on the roof and was very good, and the staff attentive.
There is a pool in the centre of the hotel but we didn't use it ourselves.
If you want a hotel out of the main area (but still within walking distance to the main square and Mosque), I would recommend this - although finding it once you arrive in Marrakech may depend on a bit of luck. If I were the owner I'd look at providing a pick-up service.
