We came as a family with two small children and would like to thank John for the very pleasant stay.
John was waiting for us when we arrived, explained everything to us and gave a lot of useful tips. You could have contacted him throughout your stay if you needed help, but that wasn't the case with us.
John's apartment is very nicely furnished. There are two bedrooms and two bathrooms as well as a living room with a comfortable couch, a dining table and a small but adequate kitchen. In the kitchen you will find everything you need including a coffee machine and a microwave. Everything is clean and tidy. It has wifi and a tv.
The apartment is in a pleasant neighborhood with supermarkets just a short walk away. The O2 Arena can be reached by bus in about 10-15 minutes. As a woman, I had no qualms about walking the path alone at night. While it's a little further to central London, it's easily accessible by Tube, National Rail, or Uberboat. Note here from us - if you are traveling with children or are sensitive to noise, you should not take the tube. It's terribly loud. Better to switch to train or ship.
We can therefore only recommend John's apartment, especially if you are looking for something close to the O2 arena.
