Jon has been a great host. Even though we didn't have the chance to meet him, he made everything for our stay at his place to be great, from beginning to end. He has been available at all time and always responded really quickly to my messages. He even let us stay at his place the whole day on our departure day which was really appreciated as we didn't have to carry our luggage through London for the afternoon.
The appartement is amazing, even better than on the pictures, and very well located.
I highly recommend staying at Jon's.
