Karen and her parents are very helpful, just ask them if you need anything or have questions. The room was nice and clean, the host friendly and you should be ok with kids running around in the house as mentioned in the description, they were just nice and not too loud.
If you have heavier bags, it might me not too optimal as you have to walk about 10 to 15 mins from the busstop.
All in all it was nice to stay with Karen and I can recommend it.
