We stayed at Dar Azawad for two nights, with a night in the 'charme' camp at Chigaga in between. The first night at the hotel, we were in a standard room, which was very comfortable - would have been happy to stay there a few more nights. The second night at the hotel was in one of the nomad rooms - which I would avoid if I was ever there again. The ceiling of the room was very low, and it only has two tiny windows. As a result, it feels very enclosed and dusty/sandy. The quality of the beds was also much less than in the other room we stayed in.
The food at the hotel is really of an excellent standard - far, far beyond what you would expect in such a remote location - it would easily compare with a good restaurant in a big city. However, they allow smoking both in the bar and the dining room - which wasn't a problem one night, but was a big problem the second night when we were next to a large table with lots of heavy smokers.
The tented camp was not really up to the description on the website. Yes, the dunes are spectacular - but the really loud generator noise is very intrusive (yes, I know you need a generator to have electricity/hot water, but given the price you pay for the tented camp, you would expect them to find some solution to reduce the noise). The tents are very attractive and well spread out from eachother - with full bathrooms which is indeed a luxury - but in our tent there was a major leak from the bathroom into the main part of the tent which meant we didn't have hot water and the carpet in the tent was soaking wet for all our stay - and though the manager eventually managed to fix the leak, no one did anything about the carpet.
For a hotel and a camp in the middle of nowhere, it isn't bad, the food is outstanding, and the locations are stunning but I've been to places that were just as remote but had better service.
