My son stayed with LuLu for 6 weeks while in San Fran. The room was spacious and clean with regular clean towels, sheets and room cleanup weekly. The neighborhood was lovely, safe, and close to the Muni line so getting to and from San Fran was sooo easy. There were various amenities nearby - restaurants, drug store, movie theater, laundry. There was an opportunity to meet and break bread with other folks every evening if desired. For his first time away by himself without family, my son felt comfortable and safe and we felt the same way despite being on the opposite coast.
Lulu says she will be a Mom to you and she does wish to provide and be the best host she can be. If you are a person who is very private and does not wish to be Mom-ed, you can do that too. Her house is spacious and despite being able to comfortably accommodate a number of guests, you don't always run into them.
There are rules to the house to keep it safe and clean and guests are expected to follow them (esp. where the alarm system is concerned). this is important and contributes to all the guests feeling safe. There is a no-lock policy on the rooms and this was NOT an issue in any way. If you feel weird about that, bring your own luggage lock but guests respect each others spaces.
