Stayed at Mark's place for six nights. The place is just like the photos and is in a great location near the airport.
Kitchen is fully stocked with whatever you'd need to cook (we didn't) and having the washer/dryer, wifi, and dish network were great extras.
Rent a car...its a great spot to explore the island from. It isn't needed, but it definitely gives you more freedom to move around.
Don't worry about being too close to the airport it's actually pretty cool seeing the planes up close right from the balcony. Plus, there aren't really many flights after sunset anyway.
Thanks Mark and hopefully we will make it back to SXM.
