We found Riad Andalla to be an oasis to retreat to after all the hustle and bustle of the medina. We enjoyed the warm welcome, the lovely mint tea, the two relaxing inner courtyards (the riad occupies two buildings divided by a common footpath) and the tastefully decorated rooftop garden - the views over the Jemaa el-Fnaa were fantastic day and night and we never grew tired of having breakfast there every morning. Our room was equally interesting, with lots of Moroccan elements built into its design. The air conditioning was powerful enough to keep the room cool (though we've been told that it's been an incredibly mild summer there), and the beds were comfortable. The shower had reasonable water pressure but it was evident that the plumbing can only handle so much - an average length shower took 1-2 hours to drain. For those looking for hotel-style bathroom amenities, you should reset your expectations. Unlike older reviews, all of the rooms we saw could be padlocked for security.
The service was always friendly and we thoroughly enjoyed the delicious (but comparatively pricey) tagine that was served (remember to book this ahead of time). Location wise, the Jemaa el-Fnaa and the souks are both a 3 min walk away, and most of the major attractions (palaces and gardens) are within walking distance.
The riad can be difficult to find the first time - check out other reviews for walking directions (use Cafe de France as the reference point). For navigation, use the Maps.Me app.
