I definetly recommend staying with Louis and Ludovic. They were very nice and attentive all the time, since the beggining. They always offered clear information and even had their own guidebook regarding basic information of the surroundings, such as alternatives for loundry, eating, etc. Also, they were very accomodating even as we had to change our plans a bit toward the end portion of the trip.
As for the place itself, it is great, just perfect: It has the privacy of having the whole place for yourself, your way in and out of the guest house is independent of the main house, it is located very centrally, so most of LAs attractions, from the beaches to Hollywood, including museums, studio parks, etc. are usually within a 30/40-minute drive radius. There is a potent A/C, quality wi-fi, an equipped kitchen, a comfortable bed and a nice entertainment set-up, with large flat screen, DVD, Cable and even a drawer with some classic DVDs. There's a modern refrigerator, a good closet, large mirrors and a live-saving coffee maker. Also, the place was pristine.
