The whole process was very easy to use. I've used other services like Airbnb and this was much better. I was able to find Marylyn's very nice studio and communicate with her directly via the site, text and email. I was able to keep her informed of my itinerary as it changed. She always responded quickly and let me know not to worry. She was there when I got there. The studio is clean with thoughtful items, like bottled water, milk for cereal, coffee etc.. These are things you have to earn a bunch of points at a hotel chain to get. :-) This wasn't a tourist trip, so I didn't need to worry about subways and nearby attractions and eateries, though there are plenty around where she lives and I'm sure Marylyn can give you some advice if needed.
All in all, I'm glad I booked her place and will definitely stay again in the future.

p.s. I have a sneaking suspicion that Marylyn and her family are excellent cooks, though I haven't eaten anything. The smell of homemade Caribbean food one afternoon made my mouth water involuntarily. :-) Too bad it isn't part of the room rate!
