My grad student apt has extra space for someone who is clean and looking for a quick overnight stay in a very good location near Harvard University. I have a very comfortable Japanese tatami mat located in a large foyer space adjacent to my bedroom. You can use the kitchen, bathroom, and the wifi. I provide clean sheets and towel. Check in is after 7pm and check out is before 10am. (I will post a picture soon of the tatami mat and the foyer space.)
This large foyer space comfortably sleeps one person, and connects to three rooms - the kitchen to the left, the bathroom ahead, and my bedroom to the right. You have direct entry to the kitchen and bathroom. The main door leads to the foyer. Note, for me to enter the kitchen or bathroom or to enter or exit the apt, I would need to walk through the foyer space. But I will largely not interfere with your stay and am extremely quiet, clean, and considerate. You can use the table in the kitchen to do any work or to eat.
