We love this apartment after staying here two years in a row. It is charming, just steps from a tube stop that is on the same line as Paddington (for the Heathrow Express) and Kings Cross, where we go for connections to other areas.
It is also just a few blocks from the very fun Portabello Market, and easy walking distance to Kensington Gardens and lots of pubs and shops in Notting Hill.
The apartment itself is charming and very comfortable with everything we needed, and though it's so close to so many things, it is on a quiet street so you can really relax for a quiet night. We hope to be back!
