I had a GREAT home at Lulus, during my visit to San Francisco. The house itself is located close to public transport as well as in a very peaceful and beautiful neighborhood.
Lulu is an incredibly sweet and helpful person! You will share the house with other guests and Lulus family. Therefore, you must be willing to respect all the house rules and have a quiet behavior morning + evening.
If you are a summer person, it may be a good idea to bring a warm blouse (I had that). The house is a little bit cold in the winter months.
