Wonderful! My partner and I stayed here for about a month while working remotely. Kai and Nina's place is comfortable, clean, well equipped and well decorated. Nina was very responsive and personally checked that everything was working as we settled in. It truly felt like a home away from home -- they had everything we needed for a long stay! The location is also great. Nice neighborhood, a 3 minute walk from the 69 bus to take you into Harvard Square, and about a 15 minute walk from Kendall Square (good for restaurants and visiting MIT) and the Red Line stop there to take you into Boston.
