I would highly recommend staying at Jess & Tim's flat in Clerkenwell. The neighbourhood was filled with fantastic pubs and restaurants, everything was walkable and allowed for great exploring. The flat was perfect; clean, cozy, had everything you might need and exactly as pictured. Jess is a great host! Easy and friendly communication, she pointed us in the direction of hidden gems throughout the neighbourhood. I've been to London a few times, but my experience staying at Jess & Tim's has been the best by far!
