We had 4 wonderful days in San Francisco to which Lorraine not only contributed with her little studio but also with her kindness and the tips she gave us of what to see in SF.
The studio provides everything you need on a city trip: a VERY comfortable bed to rest after all the sightseeing, an absolutely beautiful garden which you can enjoy when having a drink in the evening or breakfast, a spotless bathroom, tons of leaflets about what to do in SF, a LonelyPlanet SF, ALL the kitchen stuff you need and, like I said, a wonderful host who offered helpul advice in the big city (e.g. position of car tires when parking downhill). The area is safe and clean, in 5 min you are at Height St, just 1 block away is the bus which brings you downtown. Parking was no problem at all, even on street cleaning day.
We can absolutely recommend staying at Lorraine's studio and if we come back to SF, we'll definitely ask Lorraine to have us again.
