I'd like to know what factors they are based on. The perspective of a visitor is clearly different from a resident, but I can usually get a decent hotel in Paris or Milan for around 50 Euros, and for slightly more (and slightly lower definition of "decent" in Zurich). This is close to impossible in NY. Does anybody have a breakdown of these studies, so that we can decide both whether figures are plausible, and, more importantly, are the relevant for us, or merely relevant for bankers deciding where to put their bonuses.
