This is a very special place!
Our family stayed here for four nights with three grown children and we enjoyed it very much. The converted church is beautiful and the flat is well furnished. Our children all had rooms of their own and there was still extra space, including a nice kitchen and seating areas. The listing accurately describes the place.
It’s located a bit away from central London on the Underground Northern line and we got very used to taking the tube (Archway station) wherever we needed to go. Very easy connections to national rail. Much more convenient than taking a taxi or Uber, which we did a couple of times when the rail line was down and it was a hassle and expensive. Short story: plan a little extra time to get to the central London sights, but we felt it was worth it.
The neighborhood is not flashy and feels safe and has basic amenities nearby like groceries and cafes. Not a great restaurant area if you want to walk to dinner.
It’s also an easy walk to Hampstead Heath, which we visited a few times and really enjoyed it, including their famous swimming areas!
Bottom line: we were very happy with our stay and would stay again if we went back as a family.
