Kai and Nina are great hosts and their place is beautiful. We arrived very late at night but they were very accommodating about helping us check in at the late hour. Their place is very clean and nicely decorated, and had plenty of space. The neighborhood has everything within a quick walk - full grocery store, restaurants, coffee shops, etc. Kai and Nina provided us a wonderful list of suggestions on arrival, with mini-reviews of all the restaurants and coffee shops in the area. We come to Cambridge regularly to visit family and will definitely stay with them again!
