Listen to Ann and she will take great care of you. Ann has lived in Oakland for many years, and she is very invested in her neighborhood in Tamescal. She expects her guests to be respectful of her and her home, and she will be respectful to you.
My parents spent the holidays in one of Ann's apartments next to her own home. Wow, what a location! It is one block from the best part of Tamescal with easy access to some of my all-time favorite restaurants (Burma Superstar, ShangriLa, Bowl'd Korean BBQ, and LaneSplitters Pizza) and well as my favorite ice cream shop (Curbside Creamery). While her home is only a block away from all this good stuff, it is hidden behind fruit trees with a little garden in the front and back. I was amazed how private it felt while still being so accessible. Ann, who lives in the house next door, even has chickens and geese. (So if you ever have leftovers, just ask and she will be very happy to let you feed her birds.)
Also your reserved parking space in Ann's private parking lot that comes with the rental is wonderful if you are renting a car, since parking is sometimes hard to come by that neighborhood during peek dinner hours.
Ann took great care of my parents and even left them an extra Christmas cookie treat on their doorstep Christmas morning. Just know that this location is a bit of walk from BART if you don't have a car and be very clear with your plans with Ann, and she will take great care of you.
Have a great stay in Oakland!
