The apartments themselves are brand new and they are very nicely furnished. They have all the basic necessities but you'll need to bring all spices etc if you plan on doing any cooking. Some homes you go to have at least a basic pantry to get you started.
When we booked this place, it was not clear that we were actually booking two separate neighboring apartments. It was not a big deal but if you want to hang out in 1 common space, you'll have to cross the hallway to the other apartment. And with a big group, there is not really a space to eat together with a large group.
The neighborhood is on the rougher side, but we never felt unsafe. It is a 3 block walk to the BART station and about a 10 min walk to the Ferry at Jack London Square.
