Replace Ancient Cast Iron Steam Radiator with Modern Flat Unit

I am renovating a condo in a pre-war apartment building in NYC. I want to replace a single pipe steam cast iron radiator with a modern flat wall mounted units. Does anyone have any advice/experience with this kind of project? Vendor recommendations would be helpful as well. Thanks.

    Do you have independent control of the steam delivery to your unit? Basically your own thermostat?

    A modern steel rad may be nicer in appearance, but it doesn’t have the mass of a cast iron rad and it may perform differently even if it has the same btu rating.
