Scheduled the apt by phone with Matt, he as terrific. Repairman called ahead, came on time. Wasn't great at keeping me informed (I asked him to tell me what he found once he removed the toilet, he repaired both without telling me what he found and I was within voice reach inside the house.) He was also pretty crabby, and I tried hard to lighten the mood and make him feel appreciated.
Will likely use LaMartina again but ask for a different plumber.
