We stayed for three nights in the appartment with two children (4 & 7 yrs) and two adults. All enjoyed the comfort of the appartment, well designed and nice furniture, with a lot of attention to detail!
The appartment is very nicely located and offers walking distance to various restaurants, the city centre, etc. The street is basically a safe area to walk even at night.
Parking is not easy, so mind the cost when arriving by car. There is a car park down the street to the right hand, but its 2€ per hour independent from the duration you use it.
Only down-side is that you collect the keys from the city centre office, which takes 20 mins to get to and some waiting time (in our case unfortunately 40 mins), so not too nice a start for our exhausted kids when we got there.
