The apt is amazing! There is nothing anyone could ask for, Christian and Christina provide infos about the apt and the surroundings (unfortunately the supposedly best pizza place around the apt was on summer holidays), I just loved it.
Its a 20 minutes walk, approximately, to the city center, which I liked since I was filling up on Italian food and could use the walking... also, both Christian and Christina are super helpful and quick with replying, so thank you also for that! :)
