I stayed in the Mission 16th Street building twice with Landmark Realty and you can guess that if I went back to stay with them it must have been great. Although one thing I would like to warn you about is that the neighborhood is not the one with bed of roses, the street particularly in front of the building is one of least clean ones with lots of homeless people and roadside vendors. I didn't really mind that because somehow I didn't feel scared by all that. But the great thing is that just a couple streets away is the most lively street of SF - Valencia - so I was happy, so many places to eat and groceries around. Bart is literally just 2 min away and lots of buses as well. The apartment has everything you might even for extensive cooking and they give tons of towels and beddings, etc. Perfect for a long term stay. I have stayed once for 3 months and once for 1.5 months and had a great time there. If you do go on the rooftop, please be careful because you can get locked out. The 360 degree views from the roof are amazing. There is a great amount of closet space and a very spacious bathroom and kitchen.
