I'd probably give 2 stars, but the apartment seems to be a full-time airbnb in council/social housing, which is morally questionable and possibly illegal
Pros: accessible part of town near Regent's Park; David was responsive; easy check-in
Cons: appears to be in council housing; there was mold/mildew in both the bathroom and bedroom; you can only control the shower temperature from the boiler in the kitchen (and the shower head was partially broken); there is a balcony but the door was jammed and you couldn't get out on to it
