The residence was clean and had all amenities necessary to spend a night. Communication was very good and we received all necessary information concerning Check-in/-out, as well as printed explanations of how to enter the building (there were lots of doors and keys) and some recommendations for places to eat/drink/visit. For spending a single night it was a good place, and the location made exploring the city on foot very easy.
However, some points to raise:
The street next to the house was small but very noisy at night and especially in the morning (lots of busses passed and the windows did not properly shield the noise) so sleeping might be difficult without earplugs.
Additionally while showering in the morning, the water kept turning very cold suddenly and stopped on two occasions totally, leaving us soaped but unable to finish our shower. Through the walls we heard other tenants complain too, so it clearly was a systemic issue, although we might have just been unlucky that day.
