My girlfriend and I stayed in one of the suites there while on internships to the bay for 4 months. While the building itself seemed a bit old, the studio we stayed in was beautiful. It looked exactly like the pictures on their website, with wood floors, new appliances and a tiled island counter in the kitchen.
It was amazingly furnished, with every kitchen supply one could need, hangers, and even garbage bags, dish soap and toilet paper to get us started.
The laundry machines were a bit wily, but at least we had the convenience of having them in the basement of the building.
Landmark lets you pay online, which was nice, and the response to our maintenance requests were always prompt. With the prorated rent and the inclusion of utilities for the first three months, the rent was very fair (for SF)
The area is a bit loud, and, being next to the 16th St Mission BART station, the area is a bit sketchy. However, the building is secure and we never had any issues with safety.
