Having only two nights in Marrakech we wanted to stay somewhere within waking distance of the souks and Place Jemaa -el-fna. Riad O2 is located up near Zaoia Sidi Ben Slimane, no matter how detailed a map you obtain you will not locate the Riad as it is tucked down very small alleyways, as such arranging a transfer from the airport is a must. Once at Riad O2 we were welcomed with traditional mint tea and shown our room. There was no outside look on the door which was a bit worrying at first but since access to the Riad is restricted by staff (no keys provided to guests at all) is was not a problem.
The staff are all very friendly and welcoming and offer good advice for the sights to see especially with limited time. The best bit for us was the jacuzzi and fires especially as cold in the evenings (feb).
Although the location is still in the medina it is towards the northern end and requires a prompt hike via the souks to Place Jemaa -el-fna which takes 15-20 mins. This is all part of the fun and once you recognise a few buildings and shopkeepers making it back even at night is easy. Be prepared to spend a few dirhams for directions the first time as Riad O2 is not very easy to find and the locals are all keen on showing you for a price !!
Overall we had a fantastic stay although 2-3 nights in Marrakech is enough as so hectic.
Riad O2 also serves alcohol which is hard to find elsewhere.
