Staying at Kris' place you really have the feeling you've been handed over a cozy and personal space of someone. Therefore you feel both the responsibility and all little things of daily life of someone else's place.
Kris has been very patient with me and responded promptly about all my little enquiries about recycling and cooking tools etc for which I'm very grateful. She has been an incredibly nice host, and I would definitely consider coming back, next time I'll be in Boston.
Her flat is also in a very nice position, just back Harvard campus and very close to Harvard sq. T stop, very convenient for transportation.
