This is a 3 floor walk-up studio in a fabulous neighborhood, close to all major subway lines. The apt is in relatively decent shape and is suitable for mainly a single or possibly a couple. There's a couch that can be used for sleeping but 3 people in the apt would be very tight. The photos are representative. The bathroom is on the small side and sitting on the toilet requires an angle. There's not much working room in the kitchen if you're planning to cook, but as a hub for mainly sleeping this is a good option.
I stayed here for 4 weeks during Apr-May and the window AC + ceiling ventilator were sufficient to keep me comfortable. I had no issues with the apartment and communication was easy.
