Rachel's apartment is the reason we continue to use AirBnB - to find places like this. The location literally couldn't be more perfect - the bars and restaurants around Seaport are great, but you are so close to Wall St and the World Trade, and perfectly placed for Fulton St subway which is very connected. Being so close to the river also made for a good respite from the hustle and bustle of the actual city.
The bed is extremely comfy, the towels are fab, the shower is great (although it's in the the main room so make sure you are all good friends), and we loved coming back to relax there after a busy day. We stayed for nearly 2 weeks, and didn't want to come home!
Rachel was extremely responsive to any issues and questions, helped us with early check in and late check out, and checked in often to check we were ok (whilst also respecting our privacy).
The only thing we thought needed to be mentioned is the noise from outside is very noisy (as is most of New York). We used the earplugs provided which was enough for us, but it's just worth pointing out to anyone who may be bothered. Saying that, I am super noise sensitive and it was finde for me after I got used to it!
