Alex is great host! He was always available for my many questions, came to rescue us when we had a problem with the washing machine and even provided coffee, when our Nespresso caps didn't fit in the machine.
The apartment is really well stocked, a lot of towels, bed sheets, duvets and pillows, kitchen is fully equipped. I slept on the couch for a week (we were 2 friends traveling) - it was okay, but I would recommend the apartment for a couple. Neighborhood is great, it's 10 or 20 min waking to the tube (2 different lines), Primrose hill and many nice cafés and pubs are in walking distance and Camden Town is close by bus - when I travel to London with my partner I will definitely come here again ;)
