I can't say enough nice things about this place. We arrived here after another place (Riad Nakhla) misplaced our reservation, treated us rudely, and then booked us into a place with which we were very dissatisfied. Fed up with how we'd been treated at our initial riad, we went in search of somewhere else and happened upon Hotel Emeraude.
The place is fantastic. The staff were exceedingly helpful and accommodating. The location is perfect. If you are coming or going on a Supratours bus, you are only a few minutes' walk from the drop off point. It is located close to a gate into the medina, so relative to many other hotels, it is actually quite easy to find. If you want to be surrounded by tourist shops and restaurants, this is not exactly the place for you, but we found the atmosphere much nicer than in the part of the city clogged with touts and aggressive shopkeepers. The rooms are not large but are very tastefully decorated. Someone in a review from several years back described the rooms and bathrooms as somewhat tired and in poor condition. I think there must have been a renovation since then since the bathroom was ultra-modern and absolutely spotless. Indeed, the entire place was spotless and well kept. After our initial problems with accommodation in Essaouira, this hotel felt like it was heaven sent.
As for value, our best comparison is the riad we stayed in our first night in Essaouira for Dh 250. Emeraude Hotel was a little less than twice as expensive (we paid Dh 450), but many, many times nicer.
