Babies will have accidents - for this bassinet not to have an option to buy extra bassinet covers is really unthinkable.  Anytime the baby has a mistake through her clothes and gets on the bassinet mattress we have to wash it immediately because there is no back up - I wouldn't recommend this for any parents living in cities.  It would have been nice for some wheels on this (Maybe no wheels for safety) - as a new parent you do want your eye on the baby and it would have been nice to wheel her out to the. family room at times. Safety wise it's good.
