The appartment was great, and the location was even better. Everything you'll need is in the appartment, a shower, kitchen, washing machine, fridge, airconditing etc. It's situated in the middle of the historic part of the city with a lot of restaurants and bars nearby. You could walk to the city center in about 10 minutes, and the metro/bus stations were in five minute walking distance.
And also we've met Ulrik, and he's a very helpfull and nice guy. I would recommend this place to everybody.
