Your best bet.
I've visited Jarabacoa 8 - 10 - 12 times; stayed in 3 - 4 hotels; G J is US $25 - 30. / night, 1 or 2 persons. Small rooms; clean, hot water, A/C, cable TV; nice pool. All credit cards accepted; pleasant help; no English spoken?? Nice class of people as guests. Family type hotel, ie many small children. Secluded, remote location in farming area. Good to very good maintenance. Usually 50% - 75 % empty, esp. during the work week. Bordered by a powerful river; pleasant sound of rushing water.
Negatives: off the beaten track - @ 1/2 mile on a narrow dirt road; a car is essential; restaurant - very expensive - 10% service charge + 12% national tax. Sometimes noisy @ night; loud bachata, merengue. Mostly Doninican clientle.
Free Advice: avoid 3 & 4 day weekends; many wealthy & comfortable Dominicans take a long holiday weekend; the G J doubles the normal rates. Not worth the $. Very crowded during these weekends.
