John is a great person. I don't believe he would be offended, if you didn't invite him to spend time with you, or your group. We chose to invite him and having done so, I am glad that we did.
Aside from John as a person, the space is awesome and he maintains it perfectly. Each room was made up as if there were a drill sergeant that was going to verbally accost someone if he found dirt on the windowsill with a white-gloved fingertip, if you want to stay in and cook, there are a ton of solid appliances available, and the backyard is an excellent spot to sit and talk with your friends. If you don't have any friends, make friends with John.
I am not the sort of person to take time out of my day to write a review unless I am either irrationally angry, or very happy about my experience and my experience with John and his Airbnb deserves a five-star mention.
