Why the previous owner updated the original fuse box with a new fuse box in 1970 (and where he found it) instead of circuit breakers will remain a mystery.
No kidding - fuses were years (maybe decades?) out of date by 1970. Probably the box was cheaper, and he had previously purchased 200 or so fuses and didn't want to waste the money. But that really, really sucks.
My list - shitty, inefficient, developer grade windows. Plus, as it's an old rowhouse, it has settled, making the windows even less efficient. The settling also leads to cracks in grout.
Poorly insulated in spots.
Crappy heating unit.
The range "vent" that is incorporated with the over-the-range microwave - beyond useless. Combined with unfortunate smoke alarm placement, I can't even pan fry something without it going off. HATE. IT.
