Katharine's place was as described. The room and bathroom were clean.
We found that there was limited opportunities to eat out in the area for what we could find on our own, so make sure to ask the hosts Katherine or John for a suggestion.
Otherwise the room is well located in a residential area. The underground station is about 7 minutes walk away, and the Bakerloo line takes you to the very center of London in about 30 minutes. We stayed in Katharine's place when attending an event at the Wembley, and this room is well located for such occasions as the same Bakerloo line takes about 10 minutes to get to Wembley.
Overall a great AirBnb experience.
