Margaret welcomed us at our arrival. The apartment was located as described, in a residential area, near Kentish Town Station and many shops. The two bedrooms were nice and quiet. The heating was a bit low for december but Margaret showed us how to change the settings to our liking. Alas the stay was not as great as we anticipated :

1) There was no wifi which was one of our main request, explicitly stated to Margaret before our stay was booked.

2) There was water evacuation problems in the kitchen and the bathroom, which were inconvenient and also created a foul odor in the apartment.

Margaret was aware of the problems when she welcomed us and explained she was trying to reach the internet company, and that it was all bad luck for the water problems she was having with noticeably a washing machine that didn't evacuate water anymore (it wasn't the only thing not evacuating ...).
We accepted her apologies, were able to get fresh towels though her neighbour but the wifi never worked during our stay and she didn't offer to reimburse us for having to buy a wifi connection with BT Online. So all in all, we were disappointed and think Margaret should advertise her apartment as it really is and at lower appropriate rates given the service it provides (or not).
