Europcar was recommended by several hotels and I was very happy with their service. Very friendly driver and manager combined with safe transport. They also do tours of Port-au-Prince which is highly recommended as you don’t want to go into the wrong areas on your own.
Cité Soleil is the most dangerous place in the world according to The European Union and as I really wanted to see this area they took me there in a bullet proof car. It was an incredible experience. The traffic in Port-au-Prince can be a nightmare and it’s important to add extra time for your transfers. Europcar is highly recommended for safe tranfers in Haiti. An airport pick up to your hotel in Port-au-Prince with your name on a sign costs 50 US dollars.
