The best thing about this place is that it's conveniently located near the Newark airport, and Newark Penn Station. The room was as described, clean, and comfortable. The bathroom was clean as well, though I would have have liked if they provided towels and soap. It's not comfortable for travelers to pack wet towels, which is why they should be provided.
The house is in an obscure, dark alley. The neighborhood is not a place where you would walk around at night.
I never met the host, who doesn't live in the house. However, he does respond promptly to texts. I found him to be a little hostile when I asked if I could store my luggage bag in the house after check out time. Check out time is 12:00 PM, and he's very serious about guests and their belongings leaving by that time.
This place wasn't horrible, and probably a good value for what I paid, but I don't think I'd come back again if the opportunity.
