The location is truly unbeatable. Make sure you read the policy about not having *any* guests -- that is something I had not seen before on Airbnb, but was fine for our needs.
A few very nit-picky down sides to note:
- The wifi doesn't seem to reach the 5th floor (worked fine on the 4th floor)
- There's only one shower, and it's *inside* of the 5th floor bedroom. The water pressure for the shower is very weak.
- There is some noise late into the night and early in the morning because the neighborhood is bustling. I slept right through it. Others in the group used earplugs.
There are indeed a lot of stairs to climb but that was also fine for our group. Every other aspect of this place is wonderful.
