If you have a rental car, it's quite accessible. Mary's place is fairly close to downtown, although on other side of river from it. The place is in a nice neighborhood, safe, clean, and with lots of nice little touches like coffee, tea, bowl of snacks (chips and granola bars) and even some cold water and beer in the fridge.
There is a fairly decent staircase to get up to the top floor, so something to be aware of for those with physical limitations on stairs.
Thanks Mary!
