Totally agree with previous positive reviews. We stayed for 4 nights with our two kids, aged 6 and 2. Although we were mostly out and about, any time spent in the apartment was super relaxing due to the lovely toys & spacious rooms. We had no problems cooking with the kitchen set up.
Our coffee hot tip is Five Elephants, definitely check out Markthalle Neun (market), wine bar below is a must & for parents wanting the quintessential beer garden experience while kids play, check out the playground at the bend in the canal. Fantastic set up! We found loads of other playgrounds in walking distance.
