I don't know where the bad reviews are coming from, but obviously people had no idea what they had signed up for.
We stayed 6 days at Jnane Tamsna and found it wonderful.
This getaway is a beautiful oasis in the middle of the desert like Palmeraie, with it's lush gardens and perfect silence it's like staying in the garden of Eden. We were there for our honeymoon and found an amazingly decorated (perfectly clean) room, along with the authentic and tasteful decoration of the rest of the place. Our laundry was done every day, we received welcome cookies and tea wherever and whenever we looked thirsty. There was a cosy library where one could easily spend hours. We had a nice lounge area by our pool and the service was extremely friendly and made us feel at home, because they were not tip toeing around us all the time but were there when needed and were always very helpful and welcoming. Meryanne and her husband are very friendly and interesting people who gave us the feeling of being friends staying at their private house.
The food was okay, though we aren't friends of Moroccan cuisine and haven't really enjoyed eating anywhere in Morocco, wherever we tried it. But it was always served in a very elegant, calm and relaxing atmosphere.
This is the place if you like tasteful and natural getaways with a subtle and homey atmosphere without the classy "hotel" feeling.
Certainly, the price is up for discussion as we also feel it's slightly overpriced, but that's about the only critique and we still think it was worth every cent.
