The description of the place is absolutely accurate. It is very private and quiet in the back of the main building where the host lives. You have the yard of which a major part is taken by the pool all to yourself, complete with outdoor furniture. Martina keeps to herself and communicates via email. You find the key in a lock box and at the end leave it there. The hot tub can be heated to 104 deg in about 30 minutes, the pool is not heated.
The kitchen area has everything you could ask for to make breakfast or a quick omelet or cook pasta. Everything is high quality, none of the "it's just for rental" cheap stuff. Big TV, lots of channels, very nice shower.
There is no desk, you can work on a small table at the couch or the table outside. WIFI is fast (40 Mbit) once you connect. Possibly not the best place if you plan a work retreat to finish your book, otherwise it works fine.
If you are looking for an undisturbed pad for two to explore LA without this hotel feeling that you need to get out of the room fast in the morning, this is your place. An afternoon "at home" at the pool is a great addition to a stay in LA.
