I really recommand you Hibah's appartement !
First of all, the flat is very well located, in a quiet area and very close to the center of London by the overground.
The appartement is absolutly charming, with a typical English façade outside and a lovely decoration inside. It was very clean and we had all we needed.
Finally, Hibah is a very kind and concerned person, we communicated very well before and during our coming. Despite we had a little problem with the flush (quickly fixed), Hibah as been really reactive, and she gave us all the tips and details to get the keys, the wifi and other things. She really made sure that we had all we needed to spend a nice trip and we really did !
