Christopher was an excellent host. We had an odd travel schedule (arrived early in the morning and left very late in the afternoon) and he was super accommodating. Plus, when we had any sort of issue (we were missing a set of sheets the first night) he came over within hours to make sure we got set and that everything else was okay.
I may be a bit biased, but the neighborhood was also fantastic. Less than 20ft to the A Train and only a couple of blocks to the 1 made it super convenient to get anywhere we wanted to go in the city. Plus, being so far uptown meant that you also had a ton of cool restaurants, bodegas and a vibrant community to hang out as opposed to be surrounded by "for rent signs" and a half dozen Starbucks.
Plus, if you want to get a dose of nature or history, Inwood Hill Park and the Dyckman Farmhouse Museum are basically on your doorstep. My wife and I are already planning to stay here on our next trip back to New York.
