Had a stay at this great place for 3 nights.
It's located very central with a Safeway right next door which is open 24/7.
There is plenty of no meter parking with a 2 hour limit from monday-friday from 8am - 9pm. There is also no parking on monday, wednesday and friday from 6am-8am. So if you're planning to stay there on workdays, just look for a parking lot before you arrive!
The Wi-Fi is very fast (approx. 170mbits) and you can also use wired connection when you bring your own ethernet cable. There are no TVs in the bedrooms, there is just one TV in the dining-area. As written before by other guests, Vannida provides breakfast and fruits.
All in all a very clean place, great located with a very well equipped kitchen and enough space to have a great time in SF.
