The Brussels Louisalaan/Avenue Louise has dropped a little bit to third place, with 1,775 euros. Belgium's posh high streets are popular locations for the opening of flagship stores. They also have an important extra to offer in terms of e-commerce, due to their visibility and the opportunity for customers to come in and "meet" the products.
Following just behind the top-3 are Ghent's Veldstraat (1,375), Hasselt's Hoogstraat (1,250), Liège's Vinâve d'Ille (1,125) and Bruges' Steenstraat (1,100).
Worldwide, it's New York's Fifth Avenue topping the list. Renting a commercial property in the heart of the Big Apple will set you back 29,065 euros per square metre per annum (despite a recent drop in prices due to the success of e-commerce). Causeway Bay in Hongkong (27,884) and the Champs Elysées in Paris (13,255) make up the top-3.
