I have been booked into the Roland House for a two week stay for work. Since being here I have had the staff attempt to enter my room on two separate occasions while I was there, they attempted this without any warning. No phone call, no knock. They simply used a key to open my door. Each time they claim it was just a mistake and apologize but I feel this invasive behavior is unacceptable and they need to take many more precautions before entering a residence.
