Chie could not be sweeter or more helpful! On my first morning, she very much simplified my trip to a museum by suggesting that I take Japan Rail instead of the subway. I almost didn't go to the museum because I was intimidated by the massive subway system. Chie solved that problem in a minute! That's one of many nice things she did.
Unless you walk very slowly, one of the subway stations is only a 5 minute walk. The Japan Rail station is 10 minutes. Both make Chie's home a very convenient location. The neighborhood is cute and quiet, a nice reprieve from the hustle and bustle of the city (yet you're not very far from the most popular attractions). There are many good restaurants in the area, as well.
As many have pointed out, the stairs in Chie's house are very steep. However, I had no problem getting my carry-on luggage up and down. There are rails to hold onto.
The water pressure in the shower is great and the water will get very hot or very cold, whichever you like. The bed is heated, which is nice for winter.
Chie is wonderful and her place is a bargain!
