It is a very nice house. I stayed there for a month during my English classes. In fact, it was better than I expected and much cheaper compared to hotels. If you looking for an accommodation, I recommend this place instead of home-stay and other options. Tips: if you are going to stay less than a month, still rent it for a month, as it will enable discounts and the final price may even cheaper. BTW, most of the people there have been staying for a long time (more than a month).
The house has several rooms. Each room has different size, number of windows, etc. Some rooms have private bathrooms, some not. I suggest to stay at the second floor, as the rooms there have better windows and more light. I stayed in E3 room. To my mind, it is the best room, as it is very large, has three (!) windows, access to the backyard, well furnished. I found it very convenient for studying, as there was a lot of light and no noise from other rooms.
The neighborhood is very quite and safe. There is a huge park in 5-10 mins. I used to run there in the morning. There are several convenient buses (44, 54) that can bring you to BART.
There are a dryer and washing machine in the garage. You can use it for free. It is very convenient if you stay for a long time.
