Emil was very nice to us both by message and in person. His flatmates, whom we briefly met in the kitchen, were also friendly to us.
The house was comfortable and surprisingly quiet. Our room was okay, with a big bed, a clothes hanger, a mirror, a desk, etc., as you can see in the pictures, and lots of daylight.
The area is very pleasant, you are right next to Queen's crescent (where you can find shops, cafés, etc.) and a short walk to Camden Lock market. We actually walked all the way to central London more than once.
The only downside, and it was a big one for us, was the level of cleanliness. While the bedroom was still okay (a bit dusty, though), the bathroom should definitely have been cleaner when we arrived, and kept clean during our four-night stay. The same goes for the kitchen. While everything else was good, this lack of hygiene did not allow us to feel at home.
If Emil and his flatmates managed to improve on the level of cleanliness, their offer would be terrific, and very good value for money.
