I had the pleasure of staying in John's flat for a few months while working in London and my stay couldn't have been any better. The location of the flat is prime- it is in zone 1 yet the street is quiet, which is hard to find in London. There is a Sainsbury grocery store around the corner that is open until midnight and there are restaurants, pubs, and 2 tube stations within a 5 minute walk from the flat. Communication with John was excellent- he was always immediately reachable throughout my stay. The flat is very clean, modern, and cozy with the best appliances (especially the coffee machine and the speakers that play music in all of the rooms, including the bathroom). This flat is a hidden gem! Thanks for everything!
