Jan's place is super centrally located. We were one underground stop off of the main train station. In addition it took us less than 20 min to walk into the city center and some in our party are older so a bit slower overall. Jan was super nice and accommodating. There was an issue with the wifi and it didn't work but we arrived on a Friday and Jan had tried everything to get the company to send a technician. In the end, we managed with using our data and it seemed like this was a one time thing, so it likely won't happen again! Jan was super apologetic and it ended up not being an issue for us at all! :) we had a great stay and you will too!
He also had some great recommendations for food in the nearby area and we had some really great food.
