Just got home from 4 nights at the Linq. It was my first time staying there, and overall it was a very good experience.
I had a nice quiet room, which is important to me as a light sleeper. The room itself was clean and modern, with comfy beds and a good TV. It's not as luxurious as other 4 stars on the strip, until you get to the washroom which was super well done in ceramic with an awesome 3 x 5 tiled shower, glass surround, and a rainfall shower head. Also, the water temperature and pressure was perfect.
The location is excellent, with lots of great restaurants either in the hotel itself or very close by, and in the summer heat you can walk to most places without spending too much time outside.
