We had a great stay at Marcin's place. The location was relatively convenient to both the L/M train (< 10 min walk), there were nice restaurants nearby, and the unit was quiet and well-furnished. A couple things to note: The unit is on a second floor via a staircase inside the apartment as soon as you walk in; the neighbors are a bit sensitive to noise and doors opening/closing, so you'll want to keep that in mind when moving about late at night.
