Katie was very nice and responsive, despite being away on vacation. We really enjoyed our stay and thought the location was great. The flat was nice, but the building was a bit iffy (as noted in the description). We did have a few interesting experiences with "characters" in and around the property, but overall did not feel unsafe. The stairs are a bit of a hike just to get to the entrance, especially carrying a lot of luggage and a stroller - but that was part of the description - just realize before booking. Only minutes walk from Portobello Road and Ladbroke Grove underground, was super convenient. We felt the place wasn't quite ready for arrival, with the greeter quickly "straightening up" as we were shlepping the bags up the stairs.
