Smell of water. I think it's problem with Medina itself, and not with hotel. It wasn't that bad anyway, so nothing to worry really. I brushed my teeth in normal water from tap and nothing happened. Some people worry about it, so just saying.
From outside you can't tell what is inside this Ryad. So travelling through narrow and dirty streets is an experience in itself and you start to worry how bad Ryad is going to be. I arrived around 11pm, so it was dark already. And then shock when you see Ryad with very nice luxury and relaxing atmosphere just behind dirty doors when you cross worlds - from medina streets to Salama Ryad. Location is amazing. Car park nearby (paid, but probably 2 EUR per night) is OK. For 10-20 MAD someone can help you find hotel in labirynth of medina and transport your luggage as well. I recommend this service, if you are new into Medina/Marocco as I was on first day. It is about 4 minutes walk. To find a car parking - go via Abu Bakr Ibn Al-Arabi and turn right to just before green hill and then right uphill. Coordinates of car parking is 34.063991, -4.981803. Service in hotel is nice and it's one of the best parts of my positive experience with my stay there. Also food was pretty good - 9/10. A bit expensive, but very nice. I ordered it twice, as it was worth it. Rooms were nice and one of best Ryads I stayed in Marocco.
