We rented as part of a gathering of extended family; there were 10 adults and a 1-year-old in the house. Because we were meeting at others' homes (some rented, some not), we went up and down the hill numerous times per day. It's a challenge. It's also a challenge to get a car with low ground clearance up the hill and into the parking spaces in front of the house (we scratched our front air dam every time, although my sister with an SUV had no problem). Great views from the top two floors of the house, but a LOT of stairs (house is tall & narrow). The owner is honest in his listing about the challenge posed by the stairs and the hill, so we were okay, although by the last night of our 4 day stay I swore I wasn't doing down that hill on foot again for anything short of life and death.
The owner is very helpful, reasonable, and cooperative. I'm 75, and I think I would rent the house again.
