Amazing experience! I did not stay in this same unit, but a similar one that Sebastian made available for me and my family. The apartment was beautifully furnished, and conveniently located less than a two-minute walk from the beach/pool/restaurant/bar.
Sebastian was quick to provide responses to my e-mails as I planned for this trip. We did not need to contact him during the time of our travel, as everything was perfectly set-up and in place. We didn't have any inconvenient with check-in or finding the apartment, as security was well informed of our visit and they nicely offered to help us find the unit and bring our stuff in there.
The apartment is located in a beautiful community, safe, clean, and very well-maintained. There are two pools in this space, plenty of recreation space for children, restaurant/bar, and the staff is very friendly. We had dinner at this restaurant during our stay. The food was amazing and prices affordable.
Inside the apartment you can find everything you need for a family 4-5 people. This particular unit did not have a stove oven available, but you could count on every other appliance (including washer/dryer).
I would definitively recommend a stay in this place and would consider to come back if I were planning to return to Bayahibe.
