This is a great place to stay as a jumping off point for the area. As others have noted, it is in walking distance to the Rockridge shops/food (don't miss Barney's Hamburgers, HumBowl, or Cole Coffee's breakfasts!) and slightly longer walk to Berkeley's main drags.
The place itself is more spacious than the pictures give it credit for. We had one kid on the pullout couch in the "first" living room, one smaller kid on the sofa (with a fitted sheet tucked around it) in the next living room area, and then another kid in one of the bedrooms with a queen bed. My husband and I were in the second bedroom, and the beds/linens were very comfy! The eating area is sunny but a little small (but the takeout is so good, you won't care), and the kitchen is adequate for putting food on the table -- I wouldn't want to cook a whole day's worth of meals in it, though; it definitely has that sparse, rental feel. And no dishwasher either.
We were there in early June and it was cool/rainy outside, but even so, the apartment heats up in the midafternoon (at least 10 degrees warmer than outside). The windows are old and a few have bug screens that you can insert for the bottom six inches or so, which gave some air flow, but we really needed to keep all windows and interior doors open to get any kind of cross breeze. There are fans provided, which would likely have been essential in the summer. Fortunately, there were no mosquitos, so we just kept the windows open whenever we were there. Also, the place is on a busy street, with lots of traffic noise at all hours -- we brought our own white noise machines, so it was no big deal, but for light sleepers or those using the pullout couch in the front room, it might be an issue.
Overall, great value and a nice home base for a weekend visiting family in the area. GREAT food nearby, very clean and spacious, and easy to get to.
