We just returned from a house hunting trip in Belgium and have decided to rent an apartment in the city. However, the stroller I usually use at home is not going to work here. The doorways are too narrow for a side by side stroller and I need something with good tires because of all the cobblestones. Does anyone have a great double stroller for the city? I'd like it to fold easily for use on mass transit. Am I looking for a unicorn?😝
