You will need a car (or constantly ubering) for this place - but the neighborhood is relatively safe, don't be fooled by the zip code. It's in a quiet residential area, and you can see people walk their dogs around. I accidentally left my wallet in my car (although not very visible in the cup holder) over night and it is still there in the next morning.
Mark's place is as described but expect a little bit more people than you may think living under the same roof. It's relatively clean but due to the heavy traffic it just cannot be spotless all the time - but I understand this is a actually Airbnb where the host renting a few rooms so it is definitely understandable and I surely have no problem living in Mark's place.
