Once you've decided to stay in the medina and know your budget - this is the place! The place is recently renovated, clean and beautiful. Compared to some other riads it looks a bit minimalistic and is not as green on the inside. Yet it has style and it really depends on your own style preference. The rooms are comfortable and the bathrooms, modern. It was a bit strange to see frosted glass bathroom doors in a Riad but one can't argue. The bathrooms are nice!
Having said all that - I have to admit - I never stayed there, a friend did and he is as positive about the place. Unfortunately the Riad did not have space for my entire visit and not wanting to move Riads, we stayed elsewhere.
The best part of the Riad are the owners! Michel and Michael are extremely helpful (even if you aren't staying with them). They both speak English which is a plus in a french/arabic speaking country. Michel managed to organize a tour to the Atlas mountains for us last minute and it turned out to be lovely. We had lunch at Villa Atlas during the day trip. The place was essentially someone's house but the food turned out to be awesome...pricey for where we were but very good and tons of it!
Knowing Michel was really a plus...he is a great host! The only slightly off colour suggestion was Villa Flore. The food was not as nice as we expected - a bit too much oil in everything and the ambience of teh restaurant was a bit stuffy too. All in all though - Riad Al Massarah with Michel and Michael wins hands down! It's a bit farther away from the Main Square than some other Riads but it is not that far. Infact, it's located in a slightly more peaceful and local area as compared to Derb El Hammam. Be warned though, all Riads are entered through narrow alleyways which sometimes feel a bit dirty and damp... but you get used to get it and it's part of the experience. The Riad's themselves tend to be clean and completely different from the narrow lanes outside.
