Love my city mini double and was very sad that I finally got it when DDs were almost out of their stroller days.nbsp; Like most doubles, it will fit through standard size doors out and aboutit's about the width of a wheelchair so if the doors are handicap accessible, the city mini double will fit.nbsp; It doesn't fit through narrower household doors.nbsp; Sorry, no help with the carseats since we didn't use ours with one. nbsp;
This is same with us, except we still use ours almost every day. I've never used a car seat in it and plan to baby wear or use a snap and go while she's in a car seat, or just fully recline the seat and bundle well. I prefer the side by side over front and back, so do my kids. The steering of the city mini is amazing compared to most strollers, and it's light enough that I still easily get it in and out of my car being super pregnant. The sunshades are also an awesome unique feature and protect well against all kinds of weather.
