Are there cheap/reasonable motels within walking distance to T in outskirts of Boston?

<p>Is there anything at all around/below $100? Willing to travel by T up to 45 mins into Boston as long as T station is walkable from Hotel/motel.</p>

<p>I have looked into airbnb at someone’s prior suggestion but that is more easily used if I know well in advance what days I will be visiting…in some cases my plans for Boston travel will be last minute.</p>
