I repotted it many months ago and it was fine for a while. I think it is African Violet mix?
It is located probably four inches away from a southwest facing window (but sunlight gets blocked by a house for much of the day).
I water pretty infrequently, probably once every week and a half to two weeks.
Not sure about the tap water - I haven't killed many plants with it but it still may be sensitive?
I am located very close to NYC if that helps in knowing tap water quality.
Thanks
