John is a great host and he goes above and beyond. He is very clear about his rules and as long as one adheres to these, a great experience is awaiting. John is VERY knowledgeable when it comes to travel tips within and outside the city, history, and overall common knowledge. He was able to help us out with a parking permit, so in our case bringing a car and parking it in and around the Georgetown district was not an issue at all! We would let John accommodate us again!
