We had a great stay at Katja's place. It's in a nice quiet residential neighborhood and there is plenty walkable space. Check in was a breeze. It was a bit too cold to use the pool but that's just the temperamental weather.
The only issue to be aware of is the bedroom layout. There are three bedrooms, but one of them is only accessible through one of the other two. It wasn't a big deal for us, but less than ideal that I had to walk through the room my daughter was staying in to get to the bedroom I was staying in. Not a big deal for us, but I imagine could be an issue for others.
