We stayed in Nursel's flat for three weeks and it worked pretty well for us. Nursel is warm and welcoming (at least via email, as we never met), and super-responsive. She addressed all of my pre-trip questions promptly, checked in regularly, and responded immediately whenever I had any concerns. Chloe, who cleans the flat and assists with check-ins, was also charming.
The flat itself is quiet, bright, and convenient, and has everything you need, especially for a long term stay. The kitchen is well equipped and there is a (tiny) dishwasher, washing machine, and lots of cooking equipment. In the bedroom, there is an empty wardrobe and a few empty drawers for storing your clothes. That said, the flat is on the small side, and would be pretty crowded with more than two people. Unlike many AirBnB's these days, it's also clearly someone's home -- and there is stuff (including food in the kitchen) everywhere. It was fine for us, and many may prefer -- but it might not suit those who are looking for a more sterile environment. And although it was clean, not everything is in the best state of repair.
Nursel provides extensive notes -- really an instruction manual -- and we needed them, to figure out the hob, the oven, the garbage and the heat.
The location is sensational -- Angel is a bustling, vibrant neighbourhood with tons of restaurants, independent stores, and nightlife -- in my mind far more interesting than more tourist oriented Covent Garden or Bloomsbury -- but still very, very central. For those who are cooking and eating in, it's blessed with a sensational butcher, cheesemonger, fishmonger and multiple bakeries -- plus a Sunday farmers market. And yet, as she says, in spite of being super-close to the action, Nursel's flat is on a quiet side street. There are multiple bus, underground and overground links in proximity.
All in all, a great stay and a terrific value.
