This place is a FANTASTIC airbnb experience. I have been an airbnb Super Host for several years, and this spot has my seal of approval.
The entire house appears to have been renovated specifically for Airbnb. The front door has keypad entry, and every room in the house also has keypads.
The floors have either been beautifully refinished, or replaced with brand new wood. There are several parking spots outside the house. The kitchen has all new appliances, and is stocked with most of what you'll need.
The rooms have comfortable mattresses, luscious comforters, plenty of towels, and everything you'll need in the form of soap/shampoo/paper towels/etc. There is AC for the summer and heat for the winter.
If you have a car, any room in this house would be great for you! There is a train station about a 10 minute walk away, but I'd recommend you rent a car if you don't have one.
In summary, if you're traveling to Boston and you have a car, this should be one of the first places you consider. Don't allow the lack of reviews to deter you - it's just a new place, and it'll be getting 5 stars consistently.
Thanks Sherwin!
