We had an excellent stay in San Carlos and were made very welcome by Eric, Tammy and her husband. Tammy (Eric’s mother) had bought fresh bagels, fruit and avocados and sweets for us and even put a bowl of fresh cooked food aside for us to try, which was absolutely delicious!! Bed was really comfortable and house was very clean and back porch really nice to sit on a sunny day with beautiful views. Keep in mind though that SF is a bit far by public transport, so would definitely take an Uber.
We would highly recommend staying here!
