Everything was great but there was a beeping noise like an alarm that went on all night that was a bit annoying

Good stay despite some issues. It took three people (including a senior manager) to check me in. It was like I was the first person whoever checked in before. I think it had to do with the fact I had a condo that the hotel operates but maybe doesn't manage. Check out was also questionable. We charged a meal to the room and did not get a final invoice at check out. The sauna also didn't work. The best part were the shuttle drivers; they were great.
