Before boarding the plane bound for the Dominican Republic we had reservations for one night, Hotel El Paraiso, in the heart of the tourist village Sosua complete with all the hot Caribbean action.
We liked where we were but checked out several other hotels to stay at next. The next morning I negotiated for a long term stay at Hotel El Paraiso. I started out by asking the price for 1 week, followed by asking the price for 1 month. Next the price for 3 months if we pay cash, in advance. This worked well. We received a huge price break for a 3 month stay. $600 per month complete with full kitchen, pool, with a big patio.
