My young adult son and I stayed at Caroline's house for five nights. Selected the room based primarily on value, given London's price tag. The Putney location means you're not in city center, but transportation from Putney train station to Waterloo (or alternatively Putney Bridge tube) made for easy connections. We toured the city for five days without any transportation issues. As for the home itself, Caroline is a gracious host. Superb communication from beginning to end. Clean and simple accommodations. A warm breakfast each morning. Overall, a good price/value ratio.
