The appartment is really nice and comfortable. The living room receives a lot of daylight thanks to the big windows and the bedrooms are quiet as their windows are in the back of the building. The neighborhood is lovely and 3 minutes by foot from the Northern line Hampstead station. You'll never be in touch with "Arielle" (the person who supposedly owns/rents this appartment) : it's actually managed by an agency called Gilead and each time you'll write a message to "Arielle" the reply will come from a different Gilead employee. That said, despite the fragmented communication this place is definitely worthwhile.
