The Flatiron Institute is located in Manhattan at: 162 5th Ave, New York, NY 10010, USA. There are several hotels nearby in Manhattan, but some will be expensive; many offer a government rate, though. If you make reservations at one of them be sure to check that the rate you are quoted is for all nights of your stay. Hotel rates will rise steeply as we approach the conference dates. It is much better to make a FLEXIBLE booking now, (make sure you choose a REFUNDABLE option through the hotel website) and cancel later than it is to wait and see whether you will attend the meeting and booking last minute.

The SOC has identified one (more expensive) option within walking distance to the conference, and two others near a train station with quick service to the conference venue. The two in Jersey City are within short walking distance of each other; they  offer a range in price and quality. All prices below are for their refundable rates as of mid-January (have to specifically select on hotel website). At some, you can get a slightly lower non-refundable rate.

Approximately $325/night plus tax ($350 for two beds)

Tax for each of these hotels will add around 14% to the nightly rates. Other more affordable accommodation in the New York City area can be found in Chinatown, Hoboken, and Jersey City. All three of these have easy public transit and Uber into NYC to the conference location. If you go to Brooklyn or Queens, just make sure that you are close to a subway station. The subway is easy to use and reliable.
