Communication was great - Fiona responded to any questions almost immediately. The house was lovely and everything was clean. The only slight niggle is that if there are more than two guests and the sofabed is being used there isn't enough comfortable seating in the dining/kitchen area.
The neighbourhood was OK, a little noisy but didn't keep us awake. It was a good 10 minute walk to Peckham Rye station which is served by the Overground so the trains aren't as frequent as the Underground - something to keep in mind if you're on a schedule.
