Rhian's little mews house is a true gem. It's right next to notting Hill, which is a great area for restaurants, markets, shops! You also have a good bus connection for going central, you are in the center in no time.
The only thing that I didn't expect was that she had other guests staying too, in a different room. This didn't cause any problems - the other guests were nice but I just didnt expect that..
Nevertheless, I really would recommend staying at Rhian's, she is very lovely and helpful! You really feel at home the moment you step in!
