This room although small is comfortable and well appointed with a beautiful ensuite bathroom and private entrance.
The owners make good use of the limited space even supplying a small fridge and the room is well decorated and maintained.
The location is amazing - we stayed at Louisa's place for a concert at The Fillmore which is only a 5 minute walk away and was the perfect place to come back to after a busy day.
If you want somewhere to stay in SFO I would highly recommend Louisa's place.
