We had a really great time at Tim and Robin's. The yard is really really comfy and enjoyable, and we were at walking distance from some of the best cafes and other cool places of Silver Lake. Everything in the apartment was very neat and clean. No problem whatsoever to park in the street, which in LA is a major point.
Among the few things we regretted a bit was the lack of light inside the apartment ; being at ground level and oriented the way it is, no direct sunlight gets through the windows (at least in March). Although probably a great point in summer, being still in early spring, we were relatively cold inside. Tim was very quick to respond and brought us everything we needed in just a few minutes when we mentioned it, so it wasn't a problem for long. Also as mentioned in other comments, noise from the neighbors upstairs can be a problem. We had a hard time getting along with a very talkative dog upstairs... Finally cooking was not that easy in the apartment. Having great restaurants around helped a great deal getting around it though...
Anyway : you'll have a great time there.
