Blackbeards is a bit out of the way in Costambar.
I would not stay here unless I had a car and I have no desire to drive there anyways.
I would rather stay at the Palace right in Sosua.
This way everything you need is a short walk.
Beach, restaurants, stores, casino, massage parlours, discos, ...

Another option is Field of Dreams.
This is a nice new place right on the main road between Sosua and Puerto Plata, closer to Puerto Plata.
Playa Dorada complex (where I stay) is right across the street with casinos, discos, golf, plaza, ...
Easy to get non-tourist taxis, buses, and motos.

Personally, I like to book a complete all-inclusive package for around $800 and just use very nice and cheap cabanas and on-site action.
