Hoi has been a perfect host
She did her best to make it work ( earlier check in - late check out)
Flat as described and shown
Big enough for 8 people, very quiet place and at less than 5min from Train station
Place is clean, beds are good and sofa as well
Perfect place if you come from Gatwick or Luton by train since it's 1 station away from St Pancras
I will definitely take the flat again for my next family trip in London !
