When a place is as incredibly good as the Vanilla Sma, you doubt between sharing it with others or just keep it for yourself, but in this case I think all other tourists should know about this fanstastic place and Nelly (owner) really deserves a great opinion about her place.
Perfectluy situated (just 5 min from Jemma el Fnaa) but in a very quiet place with no problems of noise. Lovely decorated with the charm of an authentic ancient riad, but new construction and fully refurbished so you can enjoy all the advantages of a comfortable modern house and avoid the usual problems of other riads in Marrakech (such as bad smells or lack of haeting, hot water, etc). Incredible service from all the people there (not just employees but hosts), and specially form Nelly, the best host I have ever had. But, please, do not tell anyone! shhhh :-)
