Staying with Teri was truly amazing!
She sent an email with key information a few days before we arrived in NY and always gave us lots of advice on places to eat&drink. If you are planning a visit, Double Dutch coffee is the absolute best place for coffee!
The area is safe and full of amenities, including a supermarket. Very close to Central Park and subway. 125th Street is ideal if you are coming from JFK, with express A trains running every 10-15 mins (check timings on subway's website if you are travelling over the weekend).
Great chance also to spot little jazz concerts in the area and gospel choirs on Sunday.
I would definitely recommend staying at Teri's place: it will make your NY trip even more special!
