Born and raised there. Lived there in the last year and I can tell you that it has improved a lot. To get from the airport to the city is fairly easy and with the improvements made to "Las Americas" Highway, you can get to the city in 20 minutes. From Santo Domingo to Bayahibe is fairly easy to go too, as there are signals with the right directions to La Romana, and once you reach La Romana, you'll find directions to Bayahibe. Feel free to send me a PM if you need any details.
