We had a nice stay at Allison and her partner's. They were both very sociable and easy-going. We loved their house! Both the room and the bathroom were super clean and cosy. Location-wise, you are a few stops away from the city on the BART train. The ride is actually pretty fast. Transport is not the cheapest so if there are the two fo you, we recommend that you take an Uber express pool ($4) from Allison's place to Fruitvale station and then the Bart. Get a Clipper card from the airport ($3 non refundable) and top it up to travel through SF and Oakland. The clipper card allows you to take the BART, MUNI, street cars, buses... Also, get the free City Mapper app to know the best and cheapest routes to the city. You can save the itineraries to consult them off line.
Anywway, we definitely recommend this place, and if you have a chance to visit uptown Oakland, don't hesitate!
