It will be fine if you can fit a rack and mudguards. If it doesnt have holes for mounting them it the rear dropouts and at the bottom of the fork, you can either make do with P-clips from the hardware store or buy some partial fenders without support struts. Keeping lock and change of clothes at work will reduce the amount of stuff you carry every day. Fatter tires will make the ride more comfortable - 25 mm width maybe the max that will fit with fenders, many commuters use 28 or 32 mm width tires. Always carry spare tube, pump, and tools to change the tube with you.
