My bad... not really a problem with your English, in fact it might be mine. I wrote 'will be down in a minute', but that doesn't necessarily mean 60 seconds, I just meant 'soon'.
Just that it's kinda difficult if other character's actions get assumed by another, before they're posted actually doing so... We'll get totally different ideas of what's going on and events will get all tangled.
I'm going to make Rafa to come down on the other side of the building, his bike's parked there. He'll come by park. Since it's a parking lot, he might just as well arrive on wheels.
Yeah, a building with underground parking... the way he describes it, I'm guessing more than 1 level below ground too.
