This motel is ancient, but beautiful. Unfortunately, the bathrooms are located down the hall. After I returned from the bathroom, I realized I forgot the key on the counter of the room. Luckily, I saw that the girlfriend was in the room, per indication of her casted shadow dancing below the door. After several knockings with no response, I was surprised when she approached me from behind and asked why I was waiting outside. We opened the door and no one was inside. I highly recommend Aida Plaza Motel in San Francisco. Take your key with you when you use the bathroom.
