I stayed in one of the 'Victorian' rooms. Very quaint vintage furniture and decor. It was just like stepping into 1985 but with wi-fi and Keurig coffee. My room was at the back so even though this was on a busy street, I was not bothered by street noise.
The best things I found about the place were the location and convenience. There was someone on the front desk just about all the time, and although I didn't ask questions I am sure that they would have helped. Check in was very easy and you can come and go as you please. Morning coffee was available and my room had a little mini fridge to put juice. With the nice little grocery store right across the street this place is very convenient.
Very short walk to Davis square and T (10 mins) or Porter square and all the shops and restaurants these have (many). Being on Mass Ave there are also buses running right past the house.
Downsides - although the room was clean, it did have a few imperfections - could do with some updating in the bathroom to restore the grout to its white color for example. But, this should not put anyone off staying there.
