Harry was a superb host. He was very communicative and happy to answer all our questions. Check-in was easy and straightforward via lock box, and he greeted us in person on the evening of our arrival.
His house is conveniently located in walking distance to Victoria Station and many other sights, shops, bars, and restaurants. It's a really cool, modern and surprisingly quiet space in the centre of London.
The room we booked has an en-suite bathroom and thus a bit of a hotel room feel in that it's somewhat separate from the rest of the house. We were kindly invited to use the living room and kitchen as well though and were happy to find well-equipped facilities to prepare breakfast, tea and coffee.
Would totally recommend staying here.
