8/10 Very Good! (1,221 reviews)
It just felt really obvious all the different ways the parent co of Double Tree has cut corners to make hotels worse for patrons and employees in favor or shareholder wallets (despite prices being astronomically higher with no additional benefits to the patrons or staff)

9.2/10 Wonderful! (1,542 reviews)
The decor and private garden were nice, as was the self-service pantry on the 2nd floor. The destination fee was a little annoying on top of the proxy room rate, as the credit for the bar was not useful for one member of our party who does not drink. Very convenient to Old Port.

9.4/10 Exceptional! (1,004 reviews)
Everything excellent. One minor complaint would be that the beautiful and very well appointed room had a tiny bathroom with a shower than opened on to the toilet. A design fault.
