Stay at Gertrud's place was great! It is much better than it looks on the photos especially for such a price! Also Gertrud let us in a bit earlier because we had to work, it was very nice. Location is great, there bakeries around, metro station is just 1 minute away and also you can rent bikes near the metro. Everything was perfect with flat, just be aware that flat is over the road so it gets a bit noisy at night with ambulances and crowds of people on the weekend under the windows.
