I honestly don't know what could have been improved at this place. Carol and her husband are great hosts, the cottage is lovely, spacious, and clean. Not to mention the location... Santa Monica, Farmers Market, Venice Beach, Hollywoud Boulevard all within 20 minutes (and that is unique in LA).
Only pay attention to parking. Monday morning and Tuesday morning have specific rules (Carol will inform you about that) and you are not allowed to park you car facing oncoming traffic. Being Dutch this was the weirdest parking ticket I ever received ($63).
I would not hesitate to rebook this place. A diamond in LA!!
