Excellent stay at Dar 73. It feels like you are staying at friends. They went out of their way to help us (even preparing a full breakfast at 5am so we could eat before leaving for our flight).
The contrast between the modern interior and the madness (in a good way!) of the medina is fantastic.
I'd recommend taking them up on the offer to arrange the transfer from the hotel as Dar is down a couple of alleys that won't be easy to navigate if you don't know the area.
Just around the corner from the Bahia Palace. Easy walk to a few restaurants bars and ships. 10 min walk up some interesting alleys to Jemaa al fna.
It's a little more expensive than others we looked at but I'd say its good value.
