Between us, my wife and I have booked about 15 airBNB stays. Louisa and James are far ahead of the others in thinking ahead as to what guests would like, and in keeping an inventory on hand for an amazing variety of things that might run out or need to be replaced. Emails are answered promptly.
The location is remarkably good, maybe 20-minute walk to either Harvard or MIT, a bus to Harvard stops at the corner, and the subway to either and to downtown is 2 blocks away. 10 restaurants within ~3 blocks, 20 within 5, Whole Foods ~ 2 blocks.
Thorough entertainment system, the space is well-organized. Clean laundry in the basement.
