Julia and Mark were wonderful hosts. They were extremely responsive to messages, went out of their way to find a convenient check-in time and were very welcoming.
The bedroom was spacious, the bed was very comfortable and the newly renovated private bathroom was perfect after a long day of visiting. Furthermore, the house is well situated in a peaceful street in the heart of Westminster, within 10 min walking distance from 2 tube lines (St James' Park station & Victoria Station).
Overall, I would highly recommend staying with Julia and Mark!
