It had a good internet connection.
The location was good for my work (in Harrow not central London).
Otherwise not particularly clean. Airbnb regulations about covid were not followed (owner not wearing a mask; he was working in the location before we got there). It was drafty and cold (although the heaters did function).
Several of the key amenities (oven and washing machine) didn't work or didn't work very well.
You could hear the neighbours all the time (it's a 1-bed flat in an old mansion with thin walls).
Overall, this was incredibly poor value. I wouldn't recommend this place to anyone.
