I can't argue about the overall quality, the location is great, building is renovated and clean, check-in process is superb, coffee machine, toaster, dish washer... The stay is of very high quality, with good value for money.
But the apartment felt totally souless, mostly because all the accessories from the photos were not present in the apartment (candles, flowers, vases, pillows, jars, table placemats, a tuffet in the hallway).
Silverware is like in a cheapest public dining hall. The entrance door had 1cm gap and you can hear stairwell noises as if they are inside your bedroom. There is no keylock - only code, psychologically you'd want to have some kind of hardware lock to feel that the door is actually locked, my wife felt uncalm.
The apartment did not have the stated "comfortable workplace". I guess the round dining table is supposed to be the working place, but it is a glass table so computer mouse does not work on it. There is no comfortable chair, and power outlet is far from the table.
Also note that there is no safety box, the bed is two separate beds that slide in different directions on the parquet table.
