I absolutely recommend this hotel. I stayed at Residence Louzani for 3 nights, as a 20 year old girl together with two other girls in their twenties at the end of March of this year.
The hotel rents out very specious, and very clean apartments, right at the seaside. It takes 2 minutes by foot to reach the beach of the beautiful village Essaouira. The medina is also within walking distance, it takes about 10 minutes to get there.
Overall, we felt extremely welcome and the people working at the residence really did their best to make our stay as comfortable as possible. Also the area is really nice, as a group of young girls we felt safe at all times.
