I stayed at Edward's place during a week-long work trip. It was so comfortable, and suited my needs and my partner's needs. I am hoping to stay here again!
The location is really excellent - a couple blocks from Rockridge bart, all the stores/restaurants nearby, super safe. The unit in Edward's house is partially below-ground, but has windows that don't make it feel stuffy or cramped. The unit has everything we needed: kitchen, smallish dining table, desk, washer/dryer. The backyard is beautiful.
