Pros: The top pro of the stay was our host. On a five-star scale, Lolly rates a six. She was kind, gracious, and helpful. She let us use her shower when our bathroom water pressure was low, and she chatted with us for some time while we dried our laundry. The room was spartan but clean, with two beds and two wardrobes. Flat is a 5-minute walk from Camden Stables Market (which could be a con as well) and is across the street from a Morrison's supermarket. The flat itself was safe and secure.
Cons: It looked like the rest of the flat was undergoing some renovation (though the Airbnb room has been finished) so not entirely what we expected. London was hot and muggy, so our room was hot and muggy as well. Bathroom fixtures could be updated. Saturday night was very noisy from the Market next door.
Final thought: If you are looking for a basic room as a base to enjoy Camden Markets and nightlife, this location is ideal. Perhaps because I am older I didn't appreciate that aspect while trying to sleep, but I sincerely enjoyed Lolly's kindness and hospitality.
