I spent 8 months in Jason's place. He was there only in the last two months of my stay, but he is a great host, helpful and friendly.
The house is exactly as described, spacious, clean and comfortable, honestly I couldn't have asked for more. Subway stops of green and red line are within walking distance (15 minutes) and there is a bus stop just few steps from the front door. Two different supermarket are very close (5-10 minutes walking) and the neighborhood is very nice and quiet.
I absolutely recommend the place, it was a very pleasant stay!
