The East West Hotel
The East West Hotel is in Gautier neighborhood, between Moulay Youssef Blvd. and Zerktouni Blvd. Gautier is one of the nicest neighborhoods in Casablanca, because you can go anywhere on foot, there are a lot of bars and restaurants, for example, the same East West Hotel has an Irish pub below it, as well as a tea room.
To discover the city, the mosque is fifteen minutes away on foot, the coast too, but it's not a place you should go swimming. La Medina, the historic neighborhood, and the quiet Habous neighborhood are further away, but you shouldn't have to spend more than 2 euros on a taxi to get there.
