This was a perfect choice for the four of us (mum + 3 children). The flat was very cosy, close to the tube and to the shops. We did a lot of sightseeing in the morning and early afternoon, then returned to relax for a while and eat something and still were close enough to go back to the city centre for an evening walk. Thank you Stephane for all your tips and help, it would be great to come again one day.
