I stayed at Nicky's house for a few days in August and I can tell for sure she offers very good accommodation. The room is clean and spacious and Nicky is very kind to offer her guests amenities such as teabags, coffee, biscuits (plus all the necessary kitchenware!), soaps of all kinds in the bathroom etc. All of this in the very plesant neighborhood of Muswell Hill where you can experience a true (not touristy) London ambience having all the facilities at hand (tube station at easy reach, buses, shops, cafés...you name it!).
