My husband and I stayed here for 5 days during a trip to Boston this past week. The property is very clean, the neighborhood is very safe, and the owner is fantastic. He was available but never bothered us or popped in unannounced. He even let us know when there would be painters in the upstairs apartment to give us a heads up, very thoughtful but again, not overbearing.
The apartment is in an older house so some of the floorboards creak and some cabinets don't close all the way etc but honestly, it gives the apartment so much charm and helps make it feel homey instead of sterile.
The transit is about a 5-10 minute walk from the apartment and with google maps directions it literally tells you exactly where to walk and what bus/subway line to jump on. So simple. We got ready every morning and spent the entire day in the city, coming back at night and even at night the neighborhood felt safe.
Check in was simple, place was well taken care of, and Jon even gave us a heads up on some of the best places to eat/visit nearby - fantastic all around!
