John was great. Very good communication with him. He is a gracious host and loves music, and it was fun to talk with him. The room was clean, and the bed was ridiculously comfy. Could have slept a lot longer. Neighborhood was great, right on the border to Arlington from Cambridge. One issue was that the kitchen and bathroom were not clean. I have been a lot of places, and this was by no means horrendous, but a shiny bathroom area and (less importantly) kitchen would go a long way to creating a better experience for the guests. However, he did make me coffee and a Belgian waffle and veggie sausage link breakfast that was a huge plus for me.
