I'm an attorney/political analyst working on the road, and after 8.5 months on the road I'd consider myself a pretty experienced traveler. I initially booked another one of Shully's listings, but due to some ongoing issues with tenants upstairs, I was offered an opportunity to spend the rest of my month's booking at location. I normally wouldn't book a 3 bedroom since I don't need that much space, but it was a wonderful kind gesture for me to have the place to myself.
The unit has three bedrooms and two bathrooms. I only used one of the bedrooms but the other two looked just as comfortable and cozy as the master bedroom.

Impeccable cleanliness. I've been to so many Air&Bs including some very pricy units where utensils and cookware that doesn't get used as often is left dirty, but NOT at Shully's. Everything was extremely clean. I cook all of my meals and it was great to have the kitchen well stocked with all the necessary items, from napkins to spices and flatware.
The unit has no washer/dryer, but there's a great laundromat literally less than 5 mins away. It is a large, well-lit facility with its own parking, hot and cold water washes, and variety of services. I think it's open 24/7.
The neighborhood is in the better part of Bronx. I felt pretty safe walking around late in the evening and coming back from NYC late at night, BUT you are in one of the largest metro areas in the country and it does have its share of challenges, so you do have to pay attention.
Metro North and subway stations are both within 10 min walking distance. If you're into outdoors exercise this is definitely your spot. I had the best time going for runs, walks, weight lifting sessions in the part that's about 10 min walk.
There are many smaller neighborhood grocery stores within walking distance. There aren't Trader Joe's or Whole Foods nearby, but give local guys a try - I'm a pretty picky shopper and honestly the quality and selection is excellent (so are the prices!) There are a couple of larger shopping plazas about 15-20 min drive for all your big box stores as well.
A couple of things to note. As is the case for many houses, the extremely sturdy outside facade might give you the impression of perfect sound insulation, but that's not the case. How quiet the unit is (even though it's on the top floor) depends on how quiet the downstairs quests are. For part of my stay, a family with two small children was staying downstairs and they made a ton of noise that transferred upstairs. The kids started to run, scream, and bang the walls at 6:30am and without blocking headphones I wouldn't be able to work. If you're not working from the unit like I was, it might not be a problem, and I think this family was a pretty rare exception. If quiet is important for you, might want to check with the host.
Another thing that can be a bit of an annoyance is the shared driveway. I think people fall into two categories on this one- if you're used to not sharing your parking, it can be a bit much. Who wants to deal with strangers to move their cars every time you need to come and go? For the other group that's used to parking multiple cars in a single driveway it won't be a problem. Consider which group you belong to and ask questions before booking.
Overall I had a great experience and would definitely recommend this location to friends and family.
