Tania was a great host and owns a very nice building near the castle. If you don't like walking up and down the hill to get to restaurants and attractions you may want to look nearer the old town.
The apartment we stayed in was incredibly spacious with a large terrace and a well appointed kitchen. She also had a washing machine and dryer which was helpful for us as we were traveling for several weeks and needed to do wash while on the road. I would definitely recommend staying at her place.
