My family and I stayed at Elisas house during our Christmas/ New year holidays. We were there for 7 days. The house is amazing and right on the beach. Elisa is very responsive. She used to text us back within 20 minutes whenever we had any questions. Our kids use to go down to the beach atleast 3 times a day. Vega Baha is away from all the touristy places so you can enjoy the real Puerto Rico. It is 40 minutes drive to San Juan.
The house has all the modern amenities. Internet and cable connection was great. The pool was very clean and our kids loved to jump in it every chance they got. They have a solar heater. The water was warm but can get cold if there are a lot of people taking bath at the same time. We did not think this was an inconvenience at all.
Overall a great experience and we would absolutely stay at this place again if we ever go back to Puerto Rico.
