Just back from a 4 night stay at Riad Bamboo. Fantastic place to stay - can't really fault it.
Really well designed room, comfortable bed and good shower. Very considerate and helpful staff, especially Simon who gets the balance between professional politeness and casual friendliness spot on. Lovely breakfasts on the roof terrace.
The location of the Riad is perfect. On a slightly calmer quieter side street, but just metres from a main thoroughfare. As stated, it is just two minutes from the Jemaa El-Fna and main souks (some of the maps on Tripadvisor seem to show it in the wrong place I think). All the main attractions in the Medina are within comfortable walking distance, and places further afield, the Jardin Majorelle for example, can be reached by a short taxi ride for 20 Dirhams (less than £2). This great location means it's lovely to be able to take the occasional break from the frenetic city outside, and the stylish courtyard or roof terrace are both lovely places to do so.
The only possible negative I can think of is that there is a bit of noise at night (both from outside and (only on one night) from others staying in the riad). This is just part and parcel of staying in a beautiful old building in the Medina though as far as I'm concerned.
