We enjoyed the stay, thanks to Alex for welcoming us and helping with first questions very quickly.
The apartment is located in a good walking distance from Notting Hill Gate Underground station and a supermarket just a few steps from the station. For discovering Notting Hill and Kensington Gardens itself it is also a good location.
There is also a bus stop practically in front of the house with buses passing quite frequently (which we did not use).
The many bedrooms with their own bathrooms allow a stay for guests who enjoy a bit of privacy: our daughters loved having their "own" bathrooms. The kitchen is well equipped.
