It’s a great place to stay, Melonie is an Angel, and it will treat you with respect and with her heart.
The place is close to everything, transport (Claham Common and buses) which is the most import thing when you visit London.
Melonie allowed me to make a late check-in, British airways delayed twice my flight which end up to come to her place very late at night, however she waited for me and show me her place and whereabouts at the time I arrived, almost midnight.
Follow the rules of the house and all will be fine.
