Charlie was an awesome host. Friendly and responsive, he came through in the clutch when we needed him most when I accidentally locked the keys in the flat. Charlie was the MVP of my experience.
The flat was comfortable and felt like a home, not a hotel, which was nice for a longer stay. The host is dog friendly with an outdoor yard-- perfect for our little Boston Terrier.
I'm not familiar with London and we stayed here to be close to my wife's family during the holidays, but it's not terribly convenient as we had to take the bus or Uber to an area with shops. Not a big deal, but worth noting.
