I had a great time in Notting Hill ! It truly is my favourite district in London. It was a small but quite convenient place for a single person. The situation is perfect - you're 20 min to everything in London as the underground is 2, 3 minutes away. Lovely little cafés around the corner, nice restaurants ...The building in itself is very pretty and the neighbourhood is charming and very safe - even for a female solo traveller. Will definitely come back.
