The room was as described and big enough for 2 people. Many people said the bathroom was a bit cramped but that's wasn't a problem for us. The room is very close to the Bart station that can get you downtown in about 15-20 mins and near some cute cafes to grab breakfast before you head out for the day.
In order to get into the room you have to enter a key code into the gate to the backyard and then enter another key code into the door to the garage. The door to the actual room is in the garage and locked with a regular key. Before our stay, the plexiglass panel to the garage door was blown out rendering this door completely useless. The door could easily be unlocked by just sticking your hand through the empty panel and turning the knob on the inside of the door. We were warned of this before we arrived but it did seem a bit unsafe that a door that previously needed a key code to unlock was now completely open. We stayed for 3 nights and the door was not fixed during this time.
Other than the door issue Ava was a great host - she gave plenty of restaurant suggestions, warned us about parking tickets while parking our car and was not intrusive at all during our stay.
