My family of 5 stayed for two weeks at this condo and it felt like home. Very clean and modern, right on the beach with shops and restaurants within walking distance. We would not hesitate to go this route again for a family vacation and everyone we dealt with was excellent in responding promptly and making sure our needs were met.
Just spent five nights. Infinity Blu is a wonderful compound in Sosua; unusually well-maintained, nice staff. The unit is the furthest from water and closest to the street -- but it's still set back from it. I think the location is built into the price, and it's just a 3 minute walk to the image you seen in the unit advertisement -- it really is as gorgeous as it looks here -- so no big deal. (Also, there isn't a beach, but there is easy access to the ocean for swimming and I saw someone on the staff help a resident bring the facility's kayak into the ocean for some sunset paddling.) I understand it's pretty empty in the off-season, as it was for most of my stay.
Enrique was punctual meeting me arriving and leaving. I only used the fan and no a/c, TV, etc. so the electric bill for the entire time I was there was $6.
Something I really appreciated was the large bottle of water w. the pump for drinking. You really can just show up and don't need to worry about anything. I hope to be able to visit again.
