We had a perfect stay in London. Pedro could not have been a better host. He was extremely responsive to questions and also checked in a few times to make sure the stay was going well.
As far as the flat, one could not ask for more. We were only a short walk from the Notting Hill Gate tube stop, which is used by the central and district/circle lines, really all you need to get around central London. Hyde Park and Portobello Road were also very close. Everything was clean and well-tended, and the flat was very spacious. In fact, I would rent as soon as you can, as his rates are sure to go up given all the amenities! Would happily stay here again for our next visit.
