The flat does all that it "says on the label". In fact the description you see on the AirB&B site is an understatement. Very easy to get around on public transport and to to get back to Heathrow - only GBP 3,10 from East Finchley station with a single change at Leicester Square. Good restaurants within short walk and many more on a short bus ride.
We were three adults and two kids, 4 and 6, and we had all we needed for our 8 day stay. Clean place, big kitchen with table, induction hob and the softest towels I have used for a long time.
There is a very safely designed children's playground virtually behind the flat, the kids loved it.
Only warning - if stairs are a problem to you this flat is not for you. Otherwise it is a perfect place to stay. Kim gave us the warmest of warm welcomes. She said she was freely available if needed, but we never needed any help. It all just worked well.
Thanks Kim - hope to stay with you again.
