I stayed here for three months. Here are my notes:
-- Great location. Pretty, tree-lined street, just two blocks from Erewhon market and about seven from Whole Foods. There's a cool park on Wilshire and 25th that has ducks.
-- Two wonderful trees right outside the door of the guest house. (Though their dog did poop by them quiet a bit and I chose to clean it up rather than mention to the owners.)
-- When I moved in, there was a note in the bathroom saying to not flush any paper because it might clog the pipes. You need to put the toilet paper in the trash. One thing to note is that the door to the alley where the trash cans are might be hard to push open for someone who is frail/elderly, in which case you would need to go through the front of the house and around to the alley.

-- It is moderately quiet. The kitchen/dining room where I had my computer set up and spent most of the day has windows that open right onto an alley. During the summer I had to keep the windows open. Since there's no buffer (e.g. front porch), when someone walks/drives by it is inches/feet from your window. The bedroom window faces a pretty garden but the closet connects to that same alley so in the morning I would often hear sounds like cars driving by, doors closing, lawn mowers.
-- The cat is often in the backyard and let's you pet him. The dog was usually by its owner and tended to bark whenever I walked by. It was very skittish and wouldn't come close.
