Bariloche is raving with hotels at present. I suggest you take a look at Gaucho100K `s thread about Argentina and also take a look at www.tripadvisor.com for reviews and recommendations.

Llao Llao is a very nice hotel, the nicest I would say, I haven`t seen the rooms you mention but I assume it is quite expensive and very nice too.

Design suites I`ve been told is nice but have not been there.
I would stick with the group, I`m not too exigent.
