We arrived during a very very cold week for California standards, so during the winter at night the guesthouse can be quite cold. But with the heater on, it is tolerable. At night when you sleep under the covers, you don't notice how cold it is. There are a couple small portable heaters included which also helps. Carlos is very accommodating and there was even issues with the wifi cutting off and on, but that was fixed shortly after communicating this with the host. All the amenities listed were available for us to use. The location is in a good quiet neighborhood.
