I chose Siena's place so I could walk to my doctor's appointments, and I'm glad I did. Nice room & bathroom w/shower. Not super fancy, but comfortable, with beautiful wood floor, good views, a few comfy armchairs. It seemed to be well-suited for parents travelling with youngish kids.
It IS on the 3rd floor, so from the driveway to the room it's about 3 flights of stairs. The interior stairways are both like new, in excellent condition.
I especially loved the Mission Hill area. I would come back again.
