The apartment was in a great location. You could reach everything within walking distance. For breakfast there was a bakery right next door and you are right in the city center. The apartment has a big livingroom/kitchen, but the bedrooms are quite small as well as the bathroom. We were 7 girls staying there and as there is only one mirror in the small bathroom it took a long time to get ready in the morning. I think a mirror in each room would speed up everything.
All in all it was a good choice for our 1,5 day stay. If you are planning to stay longer with a big group i would recommend something a little bigger.
