We enjoyed our stay for three nights at Cariina. The room was comfortable and staff welcoming. We were collected from the airport and welcomed with mint tea. Staff happily helped with restaurant reservations and arranged a visit to their other riads for a traditional haman. The rooms are all set round a courtyard so the only downside to that was the noise that came from other guests having early breakfasts, but I suspect this is a common feature of raids and if you are not an early riser and are easily disturbed by noise, go for a more western style hotel.
