We had a wonderful stay at Charlotte's flat. This was our first visit to London. Coming from NYC, we felt that the commute on the tube to the flat was easy. There is about a 15 minute walk from the Old Street train station. My fiance and I felt safe in the neighborhood. The flat was comfortable and charming. We happen to visit London when the temperature was 90 degrees F and humid . Luckily there was a fan and with the windows open, we slept comfortably. The mattress was decent, not too hard or soft. We landed in Heathrow at night and took some time to get to the flat because of customs. Charlotte had Goswin welcome us at the flat. There were snacks, bread, and a bottle of white wine. That was a nice touch, especially after a long flight and commute. I recommend Charlotte's flat.
