We were a family of four (with a 2 year old and 5 month old) staying for a week. We thoroughly enjoyed our stay at Esplanade.
Incredible views of sunset from indoors; a beautiful lagoon, we swam out c. 200m and were still only elbow deep; great location, we bought fresh fish from fishmonger, less than five minutes walk away, and cooked on the Weber gas bbq overlooking the beach in the evenings. There is a lovely coffee shop ( Kuumba Coffee Black River) and bakery (La Kaz A Pain) a short walk away for breakfast / brunch. Mosquitos and pests, as with anywhere on the island's coast, are a problem but is managed efficiently and effectively by Jean Claude who was easily reached throughout our stay. Would highly recommend staying here and would love to stay again when the kids are older.
