I wouldnt say painless. I scuffed my knuckles twice with the bolts near the sill and nearly burnt my hand on the exhaust. But apart from that yes. You will need a set of star alan keys or screw drivers for the ones under the seat near the sill. Also be carefull under the car if your un-doing the bolts as they are right under the exhaust and if its hot, you could get burned. But yes its easy, in Haynes terms I would give it a 1 spanner.
