My one week stay at Lucia's Airbnb was very nice. I was in town for a conference, and communication with Lucia before and during my stay was prompt and efficient. The unit is on the lower level of a typical Cambridge building, so it's just slightly below street level. Lucia and her family occupy the floors above. The place was clean and secure, and matched the Airbnb description. If you're sensitive to noise, be aware that you can hear people walking on the floor above (it creaks a bit). However, if you've ever lived in an apartment that shouldn't be a problem. The neighborhood is safe (I'm a guy, but saw lots of women and families walking around), and is a two block walk from a Trader Joe's and a Whole Foods, so you can take advantage of the kitchen very easily. It's also just a 10 minute walk to Central Square where you can catch the T (subway) or eat at one of the large selection of restaurants that are nearby. MIT is an additional 15 minute walk from Central Square. Harvard is probably a little further in the opposite direction. Overall, I found it to be a good value, conveniently located, and well hosted. I recommend it strongly and will stay there again if my travels take me back to Boston / Cambridge.
