We were Moussaabs first guests, so really had nothing to go by, but we're very happy we took a leap of faith. The flat is stylish and very well located, about 5-10 minutes from the metro, and lots of shops around. Moussaab is a great host, and quickly reacted to any problems that arose. He even cooked for us a traditional morrocan dish for our first night.
the house is right next to a mosque, so just be advised that you will hear the call to prayer many times a day, but for us it wasn't a problem.
highly recommend
