I would 100% recommend Jamal's place: it is very clean, super conveniently located close to Central 5shops and restaurants) and 10 min by foot from the Broad Institute, MIT, etc. Amenities are really good and Jamal is very responsive. I stayed 2 weeks and at the end recommended it as an address to my admin team. Very safe and clean neighborhood as well (I often came back around 10pm-10:30pm and never had issues).
