Me and my family stayed in Camilla's flat in Putney and we had the most wonderful experience. The flat is brand new, tastefully decorated and super functional, especially the kitchen. It has all the things you need, we love the 2 bathrooms and the best part is the view, it's outstanding and 180 degrees from the living room.
The locations is also very convenient to get to and from Heathrow or Gatewick airports, a few steps from the tube and the train stations (25-30 min away from London City Center)ans with lots of bus options as well. The flat is right next to the High Street with lots of restaurant and shopping options. Putney is a very cute and trendy area.
Camilla was very accommodating and Lea (the manager in London) was super friendly and helpful.
We would definitely recommend staying at Camilla's in your next visit to London we are looking forward to going back again soon.
