We had a great stay at Tim's apartment. I honestly could not imagine a better location. We could walk to Hyde Park in just a few minutes and were very close to great cafés and restaurants. His apartment is also close to many bus stops and to several tube stations.
Tim's apartment was great as well. It was immaculately clean upon arrival. There were fresh towels and linens, and the kitchen was stocked with anything you may need. We were in London in January and the flat was cosy and warm.
Best of all, Tim was a great host. Although we never met him, he was always quick to respond to my emails about checking in and out. He also contacted me a few hours after I checked out to notify me that I left my glasses behind and made arrangements to send me them.
Overall, I have nothing but positive things to say. I would highly recommend Tim's apartment to travelers. This was my first time using airbnb and I could not be more impressed.
