Stayed at Mary & Josh's brownstone for six nights and thoroughly enjoyed out stay. The apartment is exactly as described and offers ample space and amenities to really feel at home. Top floor apartment feels very private although Mary is easily contactable and very prompt at dealing with enquiries. Apartment was spotless and we really appreciated the groceries that were left out for us as we arrived on a late flight. Air-conditioning in the bedroom and living room is a real bonus in the height of summer. At first glance and when arriving late at night (and jet-lagged), the area can seem slightly daunting but we actually felt very safe in the neighbourhood and found the locals to be very friendly, often greeting us as we passed. Would definitely recommend this property to anyone who wants to see a less touristy/more authentic side of New York.
Top tip: use Utica subway stop as the ten minute walk to & from is the most picturesque.
