501 is great, given its central location it's huge. I really like the fact that it's in a residential building and feels like a home because it's not all chrome and glass.
Kitchen was well stocked with everything I needed for a 2 month stay. Shower is good high pressure and there is plenty of storage, even a walk in closet!
The super is very helpful!
The neighbourhood is absolutely great, very up and coming with 3 or 4 of San Francisco's best restaurants. Easy walk to Financial District where I was working. Most main districts are walkable.
Great place !
