Barrend, who does the tests, must have been dazzled by the trendy atmosphere at Doppio.
I have tried the doppio at Doppio. It was nothing to write home about. And for a joint that was only open for a few months, the glasses (pavina) showed signs of either overuse in the dishwasher or simply poor cleaning. If you must use glass it has to shine.
I have also had the pleasure of trying the espresso at Coffeelovers in Maastricht. Avoid the main location, and find the small Coffeelovers espresso bar at te Uni. A perfect espresso.
As regards KvdW, I have had some awful coffee from KvdW machines. Like the coffee, the machine guarantees nothing. What you need to find is a coffee afficionado behind the machine!
