Helena is one of the kindest and most hospitable people I've ever met. She was always reachable and responded quickly. She's super knowledgeable about everything London and will help you out however and whenever she can. Check-in was perfectly on time and we chatted for hours on initially meeting and that covered only a small fraction of her knowledge of London and other topics. The area is safe and lively and the walk to the tube and overground are not only short, but will take you by no fewer than 4 coffee shops, multiple cool little restaurants and other places. If you stay with Helena, you will be well taken care of!
