If you want to work from San Diego, i think this is not a good choice. I was planning to stay in this place for 6 days, work during the weekday and hang out with my friends during night and weekends. I have told the host that i would work from host's home in advance and there was no objection at the beginning.
When i arrived, i was told not to use any light in the house during the day by the host. It was dark to stay inside the house since all of the curtains were drawn during the day. Then i just pulled one curtain open since i cant use the light inside for my work and it was dark. When host came back, i was told not to pull the curtain open. The reason was to prevent the sunlight from heating the house during the day, so the house will be cooled down during the night. (yup, it was also warm inside and no A/C. There was a Fan but i was told that it was for two host's dogs. I needed to take more showers to cool myself down for the first several high temperature days). Then host asked me to not stay in the house during the day and go to Starbucks to work. The host said she did not expect me to stay in the house during the day. The host told me her electricity bill, water bill were too high. I can tell she is struggling to keep the cost low. I felt sorry about this. After this, i spend the rest of the days super carefully. Every time if there were lights on, i would explain to host that i did not turn it on. I felt a little bit anxious for my stay here.
In a nutshell, if you are traveler and will not stay in the house during the day, probably you should be fine. However, if you want to work from this place, this is not a good choice.
