If you're looking for a jumping off point for Notting Hill, this is your place.
Both Hyde Park and Portobello Road are just a few minutes walk from the front door, and we were able to explore both of those. In addition, it's close to an Underground stop and we easily explored lots of other sights in London from there.
Also, the bed was comfortable, the room was clean, and neighborhood was picturesque. It was exactly what we were looking for our first time in London.
