Natalie and Caroline were great hosts and their house is lovely. The area is fantastic as well. And I can tell - as it is my own. They took me in while my renovation project shamelessly overran. Walthamstow is very conveniently located and the tube or overground take you to any part of central London in under 20 minutes. If you want to stay local, you'll find nice pubs and restaurants in Walthamstow Village 5 minutes walk up the road.
Communication was flawless and I felt very welcome. The room is bright and spacious and I had exclusive access to a bathroom on the same floor.
I would definitely stay here again.
