Room has electronic system that requires phone or code to open, this malfunctioned leaving us trapped in the room, we had to call reception to come and let us out, very dangerous system to have in place if fire breaks out. Room was very hot and uncomfortable with no window, requested to move to room with window but was told not available, and given a fan to help, the fan did not work at all, was broken covererd in dust and second night was even worse heat wise with no window and no flowing air, we ended up leaving early to stay at a new hotel as could not tolerate another night without a window or fan. Other guests Very loud and inconsiderate, stopping, shouting and slamming doors throughout both nights we stayed
