Staying with John was a pleasant experience that we have now enjoyed twice (which says something in and of itself). John was able to accomodate us last minute this time and is always easy to get responses from. His place is comfortable, quiet and within close proximity to free street parking. John is also a great guy and a kindred music spirit. His place is the only place I've been to that houses a music collection that exceeds my own (and we are talking physical formats here, not mp3s). Very cool to peruse his collection. The last time we stayed we were also able to attend one of the music shows that he promotes. John also made us a nice breakfast each time which gave us a good start to our day. If you will be spending time in Cambridge / Somerville area you won't go wrong staying here. Thanks John!
