Fab apartment and great location.
Piers & Hedy super communicative and you can tell they use Airbnb themselves by how easy everything was and how well the place is set up.
Broadband amazing and I don't think anyone will get through all those TV channels.
Playground across the street is way better than what you get in the UK. The local kids were really welcoming to our 5 year old too. it's a really nice neighbourhood.
For runners: 10k loop gets you around the bottom of prospect park, or even better, along the Brooklyn Bridge Park and back. Head up to 15k and you'll be over the Brooklyn bridge and into the bottom park of Manhattan.
For subway: G line right outside. If you're doing the tourist stuff grab it and then change after two stops to get on the A or the C up to bulk of the Manhattan attractions in 25-50 mins door to door.
