The Tangiers is the nicest of the three towers, but the Sahara claims all are recently renovated. The main differences are that there are more non-smoking rooms in the Tangiers. Bathrooms are nothing special. Just a sink, toilet and shower with a cheap floor and counter tops. TVs are little 19-inchers.
Furniture is the standard beds and table with two sitting chairs.
Views are generally mediocre. You can overlook the Stratosphere, the east Las Vegas suburbs, or maybe a view down the Strip. This is a moderate hotel. We wouldn't say you are on your own, but expect service commensurate with the price. Some people are friendly, and we've never had a problem, but we hear reports of surly workers.
