Hi there, I am researching double buggies, and have come across the Baby Jogger citi mini double. Whilst it looks like it would fit through the front door, I am concerned about whether it's possible to manoeuvre it round the stairs and into the dining room, where it would live. Would anybody that owns one be prepared for me to borrow it for up to an hour one evening when the kids are in bed? I live 5 mins from Lordship Lane and would propose picking it up in the car, leaving you with some kind of deposit so you know I am not about to run off with it, and returning it within the hour. Thanks so much.
