The hotel is nice, it's modern and clean, and I can't really fault it.
My main issue with the stay was the area. This hotel is in the Golden Triangle, and there's not a lot there, it is totally dead at night. I'd recommend staying down the road in the town of Chiang Saen, which we did the following night, and that was great.
In the morning I asked about transport to the Opium Hall, expecting that they may have a free tut-tut or shuttle up there. They sent their hotel car around, but wanted 200 Baht for the short 3 minute ride up the street.
