Our family of four stayed in this apartment for three nights. The apartment is situated in a beautiful and quiet street in a very nice neighbourhood, a short walk from "everything you need", including the beautiful Kensington Gardens (with the BEST playground for the kids!), tube stations, cafées and restaurants.
(Breakfast from the small, busy boulangerie/patisserie "Paul" is highly recommended!)
We had a very good time in London and was really happy with the location.
We also were very happy with Stefania as out host (although we never met her in person). On beforehand she gave very good and clear information about the apartment, including how to get there and lots of other details. The apartment was tidy (is probably only used for AirBnB), and we found fruit, juice milk etc. in the fridge on arrival (not requested, just a pleasant surprise). Stefania facilitated for early check-in by placing the keys in a nearby café, and she has been responsive and very friendly in her communication throughout, even when I during our hectic first day forgot to tell her we had arrived safely in the apartment, as I had told her I would do.
When it comes to the apartment it was good enough, but I do not think the listing is completely accurate. The apartment is described as a "superb flat" and "beautifully renovated". I would not have used those words about neither the apartment nor its interior. The apartment is fine, but the standard (apart from the excellent location/neighborhood/nice building) is quite average if I am to describe it. Also it appears brighter and with a higher standard on the pictures than in reality in our opinion.
So, to sum up: I would recommend anyone to rent a place with Stefania as a host. This apartment is a good choice if you are looking for an okay apartment in this nice neighbourhood .
