Carleens place was very nice and tidy. two full bedrooms are a big plus over other similarly priced places where someone has to sleep on a fold out couch. Nice little seating area with TV. Lots of natural light in the bedrooms.
The neighborhood is nice and quiet, near the beach and not far from golden gate park. You will have to get a tram or bus to get to all the sights though, because it is not very central.
The place was nicely furnished, nice bathroom, and nice kitchen. Be aware there is no stove, so you cannot really cook. But you can have breakfast no problem.
All in all, a great place to explore SF from! I would stay here again!
