Joo is a communicative host, responding almost immediately and confirming my booking with great courtesy.
Her studio apartment is lovely with modern appliances, a clean bathroom, a comfortable bed, and fast reliable 2.4/5ghz wifi. The building is quite new with a rooftop deck and game room, a large gym, and public terraces on the second floor. It is close to amenities and multiple subway lines.
But, if you're a light sleeper, please note that because there are train tracks located right behind the building, train noise can be heard inside the apartment. Since the 7 train runs every 5-20 minutes, including all night, this can be an inconvenience. After staying there one night, I had to cancel the rest of my stay. To her credit, Joo was very understanding and approved my cancellation.
