We enjoyed our stay at Mark and Sean's apartment. The rental was comfortable and our location was fantastic - close to many bus lines, the green line, several grocery stores, and lots of stores, pubs, and restaurants. Additionally, the apartment is very secure - with locks at the entrance and at the front door. One thing to note - there are small green safety lights that stay on in the apartment in case of emergency. If you're a light sleeper, you might want to pack a sleeping mask.
