We had an awesome stay in Oakland for our family of 4 (2 adults and 2 teens) while visiting family and touring around SF.
Pros: There was a lot of space; comfortable beds; abundant kitchen supplies (plates, pots/pans, cups, utensils, etc); nice kitchen for cooking; access to the highway; great location near restaurants and stores; nice to walk around the lake; beautiful garden (redwoods on the property!!) and back deck area; place feels warm and homey; hosts are very responsive.
Cons: Master shower was a little too powerful but eventually got the hang of it with trying to maintain shower curtains from attacking us due to the pressure of the water; Master BR can get bright in the mornings (no curtains) for those that want to sleep in -- but can easily be remedied w/eye masks.
