For the most part, my stay was good. Zencity was responsive when I had questions. The place was as seen in the photos, it's in a nice area, and the bed was really comfortable. The room was pretty clean except for the floor felt a bit sticky everywhere, including the rug under the bed, so I wore socks until I climbed into bed.
I had a bit of difficulty checking in. The code I was given to enter the building didn't work for me, but there was a person inside who let me in. I also had a bit of trouble getting the door to the room unlocked - I didn't know how to turn on the screen of the keypad (tap on it a couple times and it lights up).
The elevators made me a little nervous, since they bounced a lot. Also initially the button to call them didn't work.
One of the times while reentering the building, the fob reader broke down. Luckily there was someone who walked up who lived there and knew what code to press to get in. If that hadn't happened I would have been stuck outside at night.
Despite these minor inconveniences, I would recommend this place and stay here again. It was a super easy walk to really good food places and my friends' apartment.
