I agree with Whale, the last thing I would want to see in the foyer/common property is a collection of bikes, joined by prams and car seats, then followed by whatever other stuff people don’t want to store somewhere else. By the way I don’t have anything against bicycles.
My next door neighbour has a bike, she keeps it in her apartment – we are on the second floor. Not all of the lots here have carspaces but I still don’t think the foyer is the place to be keeping stuff like that.
