Let's start with the one positive - location. On the edge of the Erg Chebbi dunes. That is where the positives end.
Negatives: Filth, fleas, dust, appalling service, dark, cold
We arrived at lunch time and were promised a camel trek at 3pm. The staff were lazing around so we didn't get going till after 4.15pm which with at that time of the year only gave us an hour or so before sunset. This in itself was disappointing. What was worse is that the camel trekker dumped us at the first dune, about 5 mins from the auberge and in full view of all of the auberges and the main highway - hardly the Sahara experience we were after! Only after insisting did he reluctantly agree to take us a further 10 mins so that we could at least pretend we were in the remote Sahara. He promptly passed out on the sand and offered no assistance with our attemps to use the sand-board we had hired at a cost of $13 from the owner. We were very disappointed as friends had waxed lyrical about their Sahara camel trekking experiences and we had ten mins on a camel!
Now to the actual stay - our room was absolutely filthy - akin to a low grade hostel in SE Asia or worse. The blankets were caked in dust, there was one light on the other side of the room to the bed and the hot water wasn't working. It was off season, we were the only guests yet not one of the staff had cleaned our room never mind checked it. We were transferred to a room with a trickle of hot water but it was equally filthy. I understand the room is supposed to re-create staying in a kasbah (mud construction) but a few lights and a hoover is not too much to ask. We had a very unpleasant and cold night and woke up with allergic coughs. Dinner was very average - over cooked skewers and an insipid salad all served by the same camel trekker in his lethargic, disinterested manner.
On departure, the owner tried to charge us $20 for the basic salad lunch we ate on arrival. As soon as I challenged the price, he dropped it down to $7 - funny that!
We have no positive memories of our stay and hope the owner reads this review and makes improvements to the auberge otherwise others will face disappointment like ourselves!
