Location deserves 6 stars: 2 minutes walk to the T (subway line), maybe 15 minutes walk and to the airport shuttle. This place has other AirBnb guests, but all were either quiet or friendly. It did not cause any problems.
Shelly and Lance are very nice, approchable, helpful and responsive hosts.
Washroom was clean with soap and towels and our room was clean as well.
I would recommend this place to anyone looking for a cheap place to spend the night and would definitely book again.
