what needs to be done?
A section of wall about 8-12" wide and about 5-6' tall needs to be replaced with either sheet rock, plywood, paneling (something) to close it back up.
The bathtub faucet in Apt B won't turn all the way off and probably needs a gasket.
The ceiling in the bathroom of Apt B has peiling paint which needs to be scraped off, spackled, primed and painted.
Note the gasket was not on the original list but it might be hard to put a ladder into a wet tub to get up to the ceiling...and its a high ceiling.
