L'Heure d'Ete is a lovely quiet Riad approximately 2 minutes walk from Jemaa El Fna (the main square). The Riad was immaculately clean throughout, comfortable bed, good shower with piping hot water, nice breakfast and extra tea/coffee if we asked for more without charge. The staff were very friendly and helpful. Had we not planned what we wanted to do they would have helped to provide us with an itinerary.
To get to the hotel you turn down an alley off one of the main streets leading to Jemaa El Fna. I've read other reviews that said that it was hard to find but we didn't find it difficult at all. The hotel felt very safe and there was a safe in the room to store any valuables with no extra charge.
We didn't use the spa facility, it's not a massive part of the Riad but looked clean and tidy. The jacuzzi was being refurbished when we were there but we were not that bothered as it was a bit cold in February and we were more interested in going out to see the city.
We drove into Marrakesh which is a bit mental, but if you just go with the flow and are not a nervous driver you'll survive. We got a bit lost and had a bit of help with directions from a local, though we did have to pay for the privilege! We found parking near by the hotel (about 5 minutes walk) but had to haggle for a good price to leave the car for a few days.
