The accommodation is as described and very good value for money when compared to other options in and around the San Francisco area. It's only a 35 minute tram ride to the bay bridge area and the tram stop is less than 5 minutes walk from Karla's place.
The neighbourhood can be quite intimidating to the out of towner when walking through it, more so after sun set, so I'd recommend a car especially for anyone with kids. We found that our 5 year old fell asleep on the tram on every return journey so had to carry her back to the house.
