The flat was very roomy, clean and new! A very large back garden, which would be great to use on a bright day. Any issues we had on our stay will not be an issue in the future since it's a new flat. For example, we were woken up very early one morning because an engineer needed access to the flat to install the network connection. I know 7:20 am isn't too early but it is too early for a holiday...
I will keep my eye on this flat for any future London visits.
