The position and the quality of the apartment is 5 stars. BUT...
One star less because we had problem with the self check in. The Cleaning Staff closed the door in a wrong way, so the digital opening didn't work. We have been 1,30 hours locked outside the apartment, sitted on the building stairs, and the Sweet Inn Client Support didn't answer, neither by chat, nor by phone. Self check in need to be improved.
One star less because the apartment is beautiful but not pratical. It have many defects. Hot water into one of the two bathroom didn't work. In one of the room you have to sleep with the tends literally over your face. Lightning lamps are really low power, in the evening you don't have a good illumination. The bathroom doesn't have space where to put towels or soap or similar, is unconfortable. And one of the blanket and one of the towels was dirty.
You really need a few precautions to improve the apartment, please make it, because the apartment really have much potential.
