So, first off, these two are peak communicators. We were in a serious bind after a different host completely flaked on us and airbnb helped us find these guys at the very last minute. Not only did they immediately respond but they got the place set up for us with about an hour's notice -- and the responses didn't end there. They were very sincere in offering help getting around, advice about the bart system, and even extra bart cards if we were going to pinging back and forth between cities.
(Like others have said) The road its on could be intimidating for some if you don't like winding narrow streets but the neighborhood is more than used to it, we didn't experience any problems. Plus the infamous stairs some reviewed about weren't nearly as narrow as I expected -- though they were quite steep. Just think of every day as leg day. The footsteps upstairs were more the usual stomping and screaming you'd expect from the young kids that they warn about in their summary, expect to be up (and stay up) by 7am.
The place is in a great location, easy to get to all areas of Oakland and San Fransisco while not having to deal with all staying in the actual city can result in. It was also immaculate and well stocked, with comfortable beds and a nice sofa -- and a shower my father fell in love with.
Overall, I'd point any friend their way if they were looking for a place to stay in the area!
