I booked the Orange room for 2 nights then extended the stay for a total of 5 nights in late April. The apartment is located in quiet neighborhood. To go to Manhattan I always took the subway line A (express) at the Utica stop. It took me 10 minutes to go from the apartment to the Utica subway stop. You can use a smartphone app (Citymapper) to check the travel time from there to your desired destination.
The Orange room is comfy for 1 person as in my case, and also for 2 people. 3 people would feel crampy in the room. It is clean and the bed has very good mattress. All the blanket, pillows, and sheets are clean and fresh.
There are two other guestrooms at the place. The quietness of the place depends on how well the other guests follow the rules and behave. I slept well 4/5 nights.
Staying in the Orange room I have to share the bath room with people staying in one other guestroom (Sky view). When I arrived, the bathroom was clean. Then for 3 days it had not been cleaned until the fourth day. The toilet is inside the bathroom, and there is only a tiny lavabo sink hardly big enough for washing hands.
The small living-room has the kitchen corner where i only used the fridge, microwave, coffeemaker, cupboard and the sink.
Next to the place there is a deli/groceries store which also prepares many types of burgers/sandwiches/wraps including vegetarian burger.
Though i only met Memo on the last day, he always answered to my various requests and questions sometime with some delay but acceptable regarding the nature of the requests.
Memo's place is definitely in my Airbnb options list for futur visit of NYC and Brooklyn.
