I'm not sure how things are in Ivory Coast these days, but the Wharf Hotel in Grand Bassam used to be a great alternative to staying in Abidjan. The Wharf is right on the beach (sand in your shoes while you eat your breakfast) and has a good swimming pool.
Otherwise, Abidjan itself has more hotels than you can shake a stick at. The Ivoire is the best known and always used to have lots of flight crew staying there - don't suppose things have changed much.
