Best place to stay if you are visiting Boston (you reach Downton in 10 min) or Cambridge. Very calm street but still very close to everything (train-restaurants-grocery). You can walk or easily bike to MIT and Harvard. The apartment is large, soooo sunny, and very comfy ! We enjoyed the breakfast on the very sunny private deck among the bird and the trees.
It was a very very nice stay. Also Jookun is very communicative and let us check out at noon :) so perfect !
