Noisy but good location.
The Hotel Indigo has a great location if you want to explore Old Scottsdale or experience the local bar/club scene, both within walking distance. It is surrounded by quite a few bars/clubs that get quite busy so at night you need to keep your eyes peeled for pedestrians while driving.
The hotel itself seems average from the outside. Reception is on the second floor of the hotel (along with the bar, outdoor patio, etc..) which is a little annoying. Other guests complained that the elevators were slow (even apologizing for stopping at reception while we were going to our room) but we thought this was a little exagerated. They didn't seem that slow to us but enough people commented that it must be the general opinion. Check-in / check-out went smooth without any sort of hassle. The service wasn't above or beyond and it wasn't poor, just average.
The pool seemed nice (no hot tub) and the wireless internet was fast. Parking wasn't an issue for us, even when we came back late at night. Just make sure to display your parking pass so that you don't get towed.
Our room was OK, however I think the materials they choose didn't work very well. For instance, our room had laminate flooring which was spreading apart in places and curling in others. It seems like a very poor choice to install a product like this. As well, we found the toilet that they used was extremely noisy, to the point that a neighbouring unit flushing would drown out any other sound (such as the clubs/bars). It seems like a little more attention to detail would go a long way into improving the stay.
The noise from the clubs was significantly greater on the weekend so if you're staying on weekenights you might not find a problem at all. While we didn't have problems sleeping with the noise I think it's loud enough that some people would.
Overall, the hotel and rooms seemed average. The location was good in terms of activities/shopping/etc. within walking distance.
