Great location! A ridiculous amount of amazing restaurants, coffee shops, bars, and touristy destinations within a 5-7 minute walk. The area was very lively but also felt safe. Surprisingly, there was not as much vehicle traffic on that street as I would have imagined, although beware it still got a bit noisy in the mornings (as is expected).
The unit itself was unique with lots space and natural light. Although it's a 2 BR unit, beware if you are traveling with friends, as the living room is not quite furnished to comfortably accommodate more than 2 people. Not a big deal for us or for couples who don't mind cuddling up on the couch, but not great for anyone unlucky enough to have to sit on one of the other chairs in the living area. Otherwise, the beds were very comfortable and they had several types of pillows, which I appreciated since I was able to find one with the perfect firmness.
Overall the host was responsive and did their best to accommodate an early check in for us (keep in mind there is a fee to check in prior to 5pm). Great stay for a couple planning to explore Boston over the weekend and see the sights!
