Matt's place was as described. A ton of windows for natural light and airy in the summer. The place is well kept, clean and comfortable to be in. The bedroom is perfect for two people. Bed is comfy and washroom has good water pressure. We had drinks one night on the back balcony that backs on to a row of trees. The neighbourhood is quiet in the summer. No issues with the instructions on getting into the place and it is about a 10 minute walk from the last subway station on that subway line. The trip into downtown Boston was a decent ride and the cost of staying out of the downtown core is good value. There is also a nice coffee shop Matt recommended that serves tasty breakfast sandwiches and decent coffee.
Only downside is that there are not many other decent food options or corner stores in the area by foot to grab any food or convenience items so I would recommend stopping beforehand to get food or snacks.
I would definitely recommend Matt's place for anyone visiting Boston!
