It was our pleasure having you as guests! Many apologies about the heat (or slight lack thereof). Since this is an older building, the heat is controlled from the master boiler in the basement and alas, individual units have no thermostats. Based on outside temperature, this master boiler is either switched on or off; as there were some warm days, the boiler must have been in the off position.
So sorry too that you had to buy an extra blanket; we have extras as well--we would have pointed them out in a heartbeat!
I'm glad that you had a wonderful time; we certainly loved offering you guys a NYC experience. Please come back soon! We'll have the blankets waiting. :)
