The Riad is high quality with good furnishings, clean and well kept. Located at the south end of the Kasbah district it is only a brisk 15 minute walk from the main Medina Square (Jemaa) and parking is relatively easy which I should imagine is not the case in the Medina.
However we found it soul-less and missing the Medina riad experience of other Marrakech reviewers.
Staff are helpful and pleasant yet distant. A request for a restaurant recommendation resulted in a visit to a high-priced (very swanky) place that would not have looked out of place in London, except perhaps in London more Morroccans would have been eating there.
Having had our booking cancelled by another (very high scoring!) Riad despite having paid 100% deposit, we were happy to take their recommendation of Henia, but we were disappointed.
If it's cleanliness, a bit of luxury (with some spa treatments on your doorstep), space and tranquility that you want (although check about the building works next door) - the Henia will be perfect for you.
If it's the Marrakech Medina riad atmosphere that you want - with some authentic Marrakech experiences, you'll be hard pressed to find it (or the guidance) at Henia.
