Depends on your exact budget. All of the following are good, there are many others.
Cheapish hotels center of town, across street from beach:
with 1 bedroom apts:
Hotel Cabarete Dominican Republic : Cita del Sol, Cabarete Dominican Republic, R?publique Dominicaine, Dominikanische Republik, Republica Dominicana
Never been inside but similar to Cita del Sol (next door):
Cabarete hotel Dominican Republic?Puerto Plata - Cabarete windsurfing and kitesurfing
Nice hotel, center of town beachfront rooms avail:
Cabarete Hotel Dominican Republic, VILLA TAINA HOTEL
center of town 2 bedroom apartments beachfront or studios with ocean view:
Hotel Cabarete Palm Beach Condos and Studios
almost new, 'luxury' 2 bedroom apartments beachfront, no ocean view, center of Cabarete bay, but 5 minute walk down beach to restaurants
Ocean Dream | Harmony - Luxury condos for rent in the center of Cabarete, Dominican Republic
Don't overlook the apartments at Palm Beach or Ocean Dream - split amongst two people, often as cheap as two hotel rooms elsewhere and nicer places to stay, in my opinion.
any suggestion for a apartment for rent or a cheap accomodation for 2 people not to far from the sea!!!!????thanks
