Having stayed in NYC on multiple occasions in the past, this was my first time booking an apartment In Harlem. The apartment itself was perfect. It was a charming brownstone, very clean and well appointed. I am a stickler for accommodations that have been detailed, with regards to cleaning, and this met my standards and then some. The kitchen and bath are nicely updated and well equipped as well.
The area where the apartment is located is a little rough around the edges and if you've never been to NYC or don't have a strong familiarity with it, it might be a little intimidating at first. I felt completely safe wandering the area for instance, but my travel companion (who was a little green) had several reservations. That being said, the neighbors on our street were so welcoming, hospitable and kind, that I almost felt like I was back in the Midwest!
With regards to public transport, there is a train just a few blocks away which is convenient. Unfortunately, it was out of commission for half our trip so the walk to the nearest working line was a bit of a jaunt, but nothing I wasn't up for as I love to walk.
The owners are very accommodating and give you detailed instructions prior to arrival. They are also very responsive if you need anything. We had a later flight and they were kind enough to accommodate our luggage so that we could see as much of the city before heading back to the airport.
Overall, we had a lovely trip!
