Katrin was an excellent host and the flat is well located near the centre. It met all our expectations except maybe the dining area. Katrin kindly lended us a portable booster seat for our baby but it couldn't be attached safely on the kitchen chairs. It's a shame as I specifically booked this apartment because the list of equipment mentioned a high chair on the ad (there isn't one).
The sound proofing in the master bedroom isn't optimal but we could move to another quieter room luckily. And the roof terrace is a perfect haven!
