This apartment is very much like a hotel with a dish washer and a kitchenette. It is not cleaned during stays shorter than a week. (that's the definition of a serviced apartment, which I didn't know before this trip)
The messages with check-in details were from the front desk and were very clear. The only thing is that when I asked a question I didn't hear back.
The apartment is closed to the center and was very clean. Check-in was very easy.
