I stayed during a business trip with my colleague.
The apartment was very clean and a lot of space for 2 people. Very well equipped kitchen and bathroom. Everything necessary for us was prepared in the place.
We really appreciated the consideration by the owner.
Just keep in mind that it's not possible to let the luggage in the apartment or at the concierge after the check-out. You'll have to use the storage (with fee) by the stations.
