We're a family of 4, with young adult/late teen children, (1 of whom has food allergies, so we need to have fridge & some cooking facilities). First trip to Prague, looking for recommendations for a 2-bedroom, 2-bath, w/kitchenette. We're all very active & can walk for miles, but want to be in a relatively central location. Anyone have a great place they'd like to recommend? We're staying 8 nights.
