I stayed at Keith’s for a week and couldn’t have asked for a better apartment or location, especially for the price. MacArthur BART is a 5 minute walk away and there are many restaurants and bars up the street for meals and entertainment (though the unit itself is far enough from Telegraph Ave that it’s very quiet at night). The bed is very comfortable, the kitchen is stocked with all the necessary items, and the bathroom (and the whole unit) is very clean. There is both a heater and a fan so temperature control is not much of an issue.
The trickiest thing is finding the unit. It is set back behind other apartments, and the area is quite dark at night, making the address hard to see. There are flood lights, and Keith offers good instructions for finding and accessing the unit. But it may be worth a Google Streetview search ahead of time so you know what facade to look for from the street.
Overall a really great stay that I would recommend for anyone looking for a simple, quiet, and comfortable place to stay close to transportation and food/entertainment.
