Buyer beware of customer satisfaction policies
I'll be as fair as I can. Lovely lobby, great location. We're currently staying for the week, but thought to get our warning out early to potentially save other people their hard-earned money.
The other reviews are accurate - small rooms, loud AC... we were prepared for this. We were not prepared for mattresses with no box springs (just wood supports = extremely hard beds), lumpy pillows like rolled up socks, and *vibration* of the bed from the loud permanent AC, which is inches from your head, given the size of these rooms, and earplugs don't stop this. Unfortunately, the warning to those considering a "boutique" hotel is that, unlike any other hotel you may have stayed at, payment is NOT due at checkout, and you cannot simply leave and go elsewhere if you are unsatisfied. From their website, carefully buried, emphasis theirs, not mine:
Cancellation Policy:
Cancellation and/or Changes must be received by The Washington Jefferson Hotel by NOON hotel time at least 72 hours prior to arrival. No Refunds, No Changes and No Cancellations. FULL PAYMENT AT TIME OF BOOKING. .
Reservations must be made with a valid credit card or the hotel will not confirm. 
So, if you don't like your room, your stay, or your trip, go jump. Whaddya want? We'll take your money first, and then nuts to you! This is New York!
Read the fine print, folks.
