Ollie's apartment is a great and welcoming space. My little boy is just over 1 and started walking during our stay in London. Ollie kindly bought a child gate for the staircase, which was wonderful but did not fit. We managed just fine but I think it might be tricky to be there with a small child.
Nevertheless, I found Ollie to be endlessly helpful and available to answer all my questions throughout the stay.
The apartment is the perfect location for a relaxed but central stay in London... bus stops and the overground are right on the doorstep and it is also a very enjoyable walk away from many restaurants, markets and other spaces. It was perfect for our needs and I would happily recommend Ollie's place to anyone who is looking for a comfortable space in this wonderfully energetic city!
