We stayed for about a week at Hannah's place and thoroughly enjoyed ourselves. The place is as pictured and we loved hanging out in the living room after a day out.
The bus stops in front of the house were very convenient, buses brought us straight to touristy spots and the underground is about 10mins away so getting around is easy from Hannah's place.
The area is great too, plenty of restaurants to choose from; having Tesco just across the street was also very convenient. We felt safe even when we came home super late.
And lastly, Hannah herself was always responsive and allowed us to check out late which we really appreciate. Overall, can't ask for a better stay :)
