My wife and I stayed at Chil's Notting Hill flat for a week. Everything was great! Chil was out of town so the housekeeper Maria met us with keys (right on time!). The flat is RIGHT in the center of Notting Hill, which was awesome - 1 block from the tube. The bedroom does not face the busy streets directly and was surprisingly quiet despite the hubbub from the street going by at night.
On the last day when my wife accidentally left her purse in the flat when we locked up. Chil was out of town, but responded quickly and Maria (bless her heart) saved us and made a special trip to come let us in. We would definitely book again!
