In Boston is almost a last minute couch. The morning we are leaving Chicago we send few more requests for Cambridge as there was no reponse for Boston. Alda immediatly answers. She is Portuguese doing PhD in airports and studying temporarly at MIT. She shares apartment with Baris and his girlfriend at the top of the stairs of the two storey building. There is a kitchen/living room where we sleep the first night in a futon, a bathroom which sink did not work well, Alda’s room quite empty where we sleep the second night and Baris couple’s room. Alda kept offering soup and tea but we only taste the latter. Her apartment is near MassAv.
