Firlian is great! He cares greatly about his tenants and does everything to keep them happy! He tries to improve the house for his guests at every opportunity he gets. The place is super clean and the clear instructions makes everybody follow the rules.
I would highly recommend this place to anyone but particularly internationals who are coming to Boston to work for a short amount of time, or students who are studying. You can feel at home at Firlian's place and meet wonderful people. The neighborhood, against all the rumors, is great too. Very friendly people, lots of schools, churches and parks around. You can find authentic restaurants nearby. The house is a nice 13 minute walk to the Jackson Square T station (can be even shorter with a short bus ride in between).
