Never get to meet up with Charlotte but she response very fast and provide a lot of information via emails and recommend lots of places (left in a thick file in the house)! I went to some restaurants and cafe she recommended!
Location - convenient and easy to find, near king cross station! My Sydney told me can be kind of dangerous in king cross area but personally still think it's kind of safe (police station round the corner)!
House - super super super clean!
Minus - no lift, so if u have lots of luggage, kind of tough as we need to take 69 steps up to her place! But we are lucky to met a nice guy who helped us with the luggage up!
