One of the reasons we decided to stay at this property was Donna (the owner)'s responsiveness to emails. She was really great with getting us all the info we needed to know. She's in the States, so we didn't get to meet her in person, but she checked in on us several times by phone, and the housekeeper who let us in, Winsome, was really wonderful.
The apartment is located on the outskirts of Port Antonio, with route taxis (100$J) passing by every few minutes to get into town. A convenience store is a couple minutes walk from the house. It's very spacious- one large bedroom with a queen bed, stand-up fan, full bathroom (cold water only), and then another bed in the living room (ceiling fan), plenty of room for 4 to sleep. There's also a 1/2 bath, laundry room with washing machine, spacious kitchen with full-size fridge, gas oven, microwave, and living room, and a entry porch. The house had cable and wi-fi. No a/c, but we found the temperature very comfortable with the fans.
There were several great attractions nearby, including Reach Falls, rafting on the Rio Grande, and Blue Lagoon, as well as several beaches.
