Folks, this is a low-budget motel in a not-particularly-special part of Berkeley. If you're looking for charming, memorable lodging for your next family vacation, it isn't for you. If your company is paying the bill, don't book this place in a misguided attempt to save them money (unless you're really, really worried about your company's state of financial health). If you're even slightly finicky about your accomodations, then at the very least pay 20-30% more and stay at one of the national chains - they're adequately represented here in Berkeley. As are a number of much nicer (and even more expensive) places.
If, however, you're traveling on your own dime and you consider a motel simply a place to sleep, shower, and drop your stuff, and you don't want to spend a cent more than necessary, Berkeley Inn is a great deal. On my latest Berkeley trip, it was the cheapest motel available - the next step up was at least $20 more. My room was small but in reasonably good shape -- a little shabby, sure, but not dirty by any means. Linens, towels, etc. were all perfectly clean. The bed was surprisingly comfortable and I slept like a baby. Shower was actually quite nice: attractive tiles, plenty of nice warm water at good pressure. There was a fridge, a microwave, a TV, and a phone, none of which I used. There were plenty of electric outlets to charge my gadgets, and free WiFi with reasonable speed to use them. San Pablo Ave. isn't exactly a sightseeing destination, but (as a former Berkeley resident) I can say with confidence that it's not a particularly dangerous area. (I arrived on foot quite late at night.) The Berkeley Inn is within a reasonably short walk of the North Berkeley BART station, AC transit bus stops, etc. so Berkeley, and the entire Bay Area, are convenient even if you don't have a car. You can walk up to Cal / downtown Berkeley in maybe half an hour.
It is what it is. If saving money is important to you and you want to get in late, hit the sack, sleep well, get up early, shower, and go out refreshed and relaxed to have a great day in Berkeley the next morning, this is definitely the place for you. If the style of your lodgings is an important part of your traveling pleasure, look somewhere else. That simple. Personally, I'll have no hesitation about staying here again next time I need a cheap room in Berkeley.
