We had an awesome time staying at Ethan's place in Venice Beach. The location was fantastic - close to the beach, quiet street in a safe neighborhood, tons of great restaurants around.
Our first night was underwhelming - the floors were pretty wet from having just been cleaned, and the bedding needed to be replaced so we did not have a comforter for the first night.
There were some common tools missing from the kitchen. The bedroom and the bathroom have some cheap stuff that work, but aren't great. There were a bunch of small, easily fixable things that individually, we'd ignore, but adding them all up, we had to take off one star. We're communicating our list to the host privately.
Overall, this was a very positive experience - but with a little more attention to detail, this can become a really awesome stay. As it is today, it might be better for shorter stays than the full month we spent here.
