Katharina and her family are super nice and welcoming. The house has all the basics covered.
It is very well located having the underground at 10 minutes and buses just meters away. You can easily arrive to the center of London in 20-25 minutes.
Even though the hosts do their best sometimes you can feel the lack of privacy.
The stairs are a bit steep and without handle, we didn't have any problem with them but we're on our 20s.
Overall we enjoyed staying and we would come back.
