Heejin was one of the most hospitable hosts - super responsive and proactively asking about our preferences and needs at all times. The place was located in a great neighborhood - close to some attractions (great bakeries, cafes, and Central Park) and close to Subway stops with easy connections to multiple lines. The neighborhood was safe and quiet. Heejin stocked the apartment with some great coffee and even checked with us about our preferences beforehand. Heejin was super accommodating in allowing us to check-out late so we didn't have to go to the airport many hours before our flight - even offered to accommodate us for an extra night in case our flight was canceled.
One small issue was that the central heating would make some noise periodically (not too problematic if you're a deep sleeper). Heejin explained that the building is from early 1800s and they are working with the landlord to allow them to change the unit. It wasn't a big problem. The place was still totally worth it!
