The location of Mad's apartment is totally awesome, we explored a lot of great restaurants (especially the restaurant downstairs provides delicious breakfasts, also we got great tips from Mads) and had a few walks along the canals. We also got a free champagne with pizzas, so it's left in the fridge for others.
Also, we are really happy, that we could've stay in the number of six people. We had a productive Friday at the apartment, all six of us working at the table preparing for the conference and the rest of our stay was just amazingly relaxing. The apartment is very comfortable, especially when it's raining outside.
