We had a lovely time in London. Katie's place is about five minutes from an Underground station and just a few stops away from the centre. The room is cosy with a comfortable bed. Even tough the house is old, the room was really clean! You can use a large (shared) and clean bathroom. The nights are silent, altough you can hear someone walking to the bathroom.
Katie is very hospitable and can give lots of advise about your trip to London. Thanks for our stay!
