To get it out the way - this place is ok. Not good, not bad.
So I will go with the good points first. Easy entrance, quiet neighbourhood, fast WiFi, clean, 20 mins cab ride to airport, train station (back bay) 5 mins away on foot, Cheesecake factory 10-15 mins walk.
Negatives - Alicia isn't a host, this is a business with studio apartments throughout the whole building. This is not the spirit of Air BnB. Place is very very small even for a studio, bed is small, no headboard, walls are thin (can hear talking both sides of room), shower has very poor power, Aircon very noisy, not really centrally located (in fairness I had not been to Boston before so should really have known this prior, just writing this for others), it's around 30 mins walk to center. Big gap under door lets light into room Not particularly cheap, better value out there in my opinion.
So not bad, not great! I have airbnb'd in Hong Kong, Australia, NYC, UK and I reckon there is better out there.
