We had an easy check-in experience to Sonia's Piccolo Studio. The Noki App allowed for convenient locking and unlocking. The area is safe and situated right next to the beautiful Irchel Park. Catch the tram right down the road. Our only complaint is that it's a very noisy area. The bells from the university are loud and ring at all hours. You also hear the tram running until 12:30 AM, later on weekends.
