I really enjoyed staying at Kirsten's and Frederic's place. They are both very friendly and the flat is very nice. The comfortable bed had two duvets which is great for anyone, who, like me, gets cold. They had provided many helpful things including a little traveller's sewing kit which came in handy and also a MOBIB travel card that you can top up. Travelers should familiarise themselves with the workings of the trams and buses and make sure you have the right change when traveling to the apartment without this MOBIB card, as the conductors don't accept over 5 euros I think. All in all a great stay in a lovely apartment, thank you!
