The apartment is located right by Copley Square, which is very convenient (lots of shops, restaurants, transportation), but also add to the noise level because it's on the 1st floor of the building. Kitchen is well equipped, bedroom is clean with good bed and quality linens. Bathroom could be better - everything is dated, bathtub doesn't drain too well, no hairdryer.
Make sure you discuss with the host all your extra needs in details ahead of time to avoid any last minute confusions. Looks like there is no flexibility once you are in the apartment.
