The apartment was as advertised, private entrance, everything clean and cozy, in a quiet street with a supermarket essentially on the other side. Pretty close to the center if you're up for some walking (~20 minutes), and has 2-3 buses stopping closeby when you get tired.
I didn't meet Sara, but she was always very nice and timely with the communications. There's a curtained door (closed) near the room entrance that has communication with the main house, but I barely even noticed the presence of Sara and her family. I'd definitely stay again.
Only word of warning for future guests is that there's little to no cellphone network in the room. The wi-fi works well though, so I really only had the need once - and it was a matter of leaving the house to the street level for a couple of minutes.
