The place had great reviews and fully lived up to expectations, I really don't think I can add much to what others have already said. The unique architecture ensures lots of light even when the curtains are drawn for privacy across the sliding door. The kitchen area is particularly well done. The one nagging point is that the shower; its adequate but small and a large person will feel cramped.
I've spent a lot of time in Rockridge, mainly house sitting for a friend, and find it an undiscovered gem. Much of the area was built in the early 20th century as single family housing, much of it in the craftsman style. College Ave is filled with unique shops and restaurants that range from inexpensive and adequate to you're lucky if you can get a reservation. And all of this is a 15-20 minute BART ride to the center of San Francisco. It's a great place to stya.
