Cozy, no-frills space - good for a couple nights. The hosts are super responsive and kind. The bedroom and bathroom were clean. Location is great, easy to get to the T and take it into Boston or Harvard Sq. There's a great coffee shop/brewery right around the corner called Lamplighter, that was convenient for picking up coffee before starting the day.
The bed was comfortable, but slightly sunken in the middle. I also had trouble sleeping the first night because the heater in the room makes a tapping/buzzing noise.
