Niko's mother greeted us and showed us around the listing. The room was as listed, not too big but big enough for the two of us. It was quite toasty when we went in July - Niko provided a fan. The room is right beside the kitchen so when other renters aren't being considerate you can easily be woken up in the morning when they are moving around there. The room is up four flights of stairs so just keep that in mind.
The location is easily accessible from the tram, we mostly just walked though and it is about 30 minutes from Old Town on foot. We walked to the castle which was about 45 minutes away. Overall, we were satisfied with our Airbnb in Prague.
