The first and foremost thing that I can say about Christian's place is that it has a great location. It is super close to the train and the metro. The Lakes has an awesome view from home and we really enjoyed morning walks there. It is close to the museums, the Stroget and also Vesterbro is around 10-15 minustes walking distance. There are several markets just around the corner whereby you can buy drinks, food etc.
The elevator was a huge help as we were travelling with a 1.5 year old.
The apartment was comfortable and clean, having basically what you may need. Also, there were several toys in the apartment. My kid really enjoyed playing with them.
I would strongly recommed Christian's place especially if you prefer a quiet place in the heart of the city.
