We stayed at Catherine's place for a reunion weekend and absolutely loved it. The location is perfect - less than a 5 minute walk to the Porter Square T station. Though close to many restaurants and other points of interest, it is still on a remarkably quiet street.
The apartment itself was clean and well maintained. It had everything that we needed to be comfortable. The train table in the corner was a nice touch as well - perfect for entertaining the two little ones I brought with me.
Catherine was super responsive and was always willing to answer my questions quickly. I highly recommend staying here.
