My girlfriend and I stayed at Kama's place for two weeks in the summer. The spot is in a great location: two blocks from the T, right next to the Lime scooter zone, and a ten minute walk from the bike share. There is also a stretch of restaurants and shops a quick walk away. Downtown Boston is easily accessible via the T or scooter/bike rentals.
The place itself really felt like home. We were able to cook a few meals and the A/C kept us cool even when it was 90º+ outside. We had a small issue with the bedding and Kama had them replaced within the hour. We definitely recommend staying here!
