Great location however this is a very noisy apartment.
Not sure what goes on upstairs but it seems to involve dragging furniture around a lot at all kinds of hours. The windows look out onto Winter Street which is busy until late at night and then the rubbish collectors are out first thing in the morning. The T trains are relatively ignorable by comparison. Make sure you pack earplugs if you need to get a reasonable nights sleep.
The closeness to Boston Common and the T trains make this a great base for walking around this lovely city or for going further afield. We had a good week here.
