First, the basic facts. This is a small, cozy apartment, I gather typical of in town New York apartments. Luxurious it is not, but the price is right. You get a cozy private bedroom, comfortable queen bed, adequate seating, storage space.
You share bath, kitchen, other amenities with the host.
The real treat is its location on Reservoir Oval. This street runs the perimeter of what was a reservoir, now is a public park. It is off the grid from the local traffic - basically the only traffic on this street is the occasional car of a resident - no horns, no noise.
The outside of the perimeter is low to mid-rise apartment buildings. Across the street, on the inside perimeter, is a park. It contains 20 acres of playing fields, surrounded by lovely woodlands and walking trails.
Mike's place is third floor, with a balcony that overlooks the park. In good weather (which we experienced), it is a lovely place to enjoy morning coffee, evening cocktails, or a nightcap before retiring. From there you look across the street at the park, watch kids playing on the fields, locals strolling the paths, many walking their dogs. A unique pastoral view in the middle of the Bronx.
Mike comes across as a very friendly accommodating host. Our interaction was a bit limited due to some pressure he was getting at work. That notwithstanding, everything (except parking) went very well. With the parking caveat, I highly recommend this as a nice place to stay in the Bronx.
