Sergey has a nice small family living in a nice small apartment, he is cooperative, nice and understanding, he provided me with an iPhone charger coz mine didn't fit into their switch, he provided me with an inflatable air mattress when my friend came over for 1 night, and the best thing he did was that when my airplane was cancelled 2 nights before the trip, he understood that and made a good refund for me for the cancelled night although he didn't have too.
The room itself is neat with very comfortable king bed and 55" flat smart TV, small over and smaller refrigerator. A/C and heater are available too.
the only cons here is that the room area is a bit small and the shared bathroom is also very small, old and overlooking the living room, a bit awkward but not a very big deal.
The Neighborhood is OK with plenty of shops and kosher foods and a nearby subway plus bus stops.
Overall I recommend this room for a business solo traveller.
