Location, Landlord, and Luxury - they're the three "L"s in AirBNB. In this case, all were excellent. You can read the other reviews for an impression of the space, what I'll say, easy short walk to two Stations, one of them Paddington, made the location great. The truly great thing was the host. This was a business trip, and I was arriving from North America and was looking for an early check in. Not only was I accommodated, but it was done with pleasure, professionalism and not "we'll charge you £100 more if you need an extra hour BS that some hosts try. Overall, I felt that I was dealt with honourably, and well. Then there was check out. I was asked when, and I asked if I could have a few more hours (my flight was later, but I had a call that I wanted to do before I left of the airport) and THAT was accommodated at no extra hassle or charge as well!
Overall, a wonderful host, great space, and I'd absolutely stay here again!
