Flavio is a great host and I believe he has a few flats in the building as the one we stayed at was not the one pictured in the advert. It was very similar though.
Unfortunately we didn't find it very clean and it felt a bit run down. We were missing a few towels and there was no loo roll so a minor inconvenience, however, the check in and check out process was super smooth.
The location is great being just 5 mins walk from the Camden Market and the price is probably appropriate but I was hoping for slightly better standards looking at photos and considering it's called a "luxurious" flat.
