Hi Laura
I have a Loola wih the car seat attachment also. God send - the car seat is a little heavier than some but for the amount of time you'll use it for it's well worth it. Clip in clip out while baby is asleep - simple and hassle free.
I too bought the loola because I wanted a parent facing system - It certainly worked for me. It's a little wider than some strollers so you might find that to be an issue with smaller shops but to be honest I never really found this too much of an issue, if at all.
I would say on the whole it's slightly heavier than most, you'll start to feel it more as the baby grows really but I have to say I got used to it anyway - they grow gradually so you just adjust naturally. Because of the weight though it's really sturdy and robust.
I have a corsa and the loola easily fits in to my boot space, it's really quite compact when folded for it's size.
I have to admit though when my LO was 6 months we bought a Maclaren XT to travel with and have been using that ever since just because it's much lighter really and our need had changed towards a forward facing stroller as LO was sitting up and looking around.
I think the loola's strongest points are it's size when folded, it's sturdiness, car seat, parent facing option. I'd say excellent for the first 6-9 month of a baby's life really.
The only downside I would have to say is the weight.
Happy shopping!
