The Renaissance is a great hotel in downtown Phoenix. They're currently under construction right now and it's kind of a cluster f at that 1st St and Adams intersection but it's not that bad. They have mock ups of how the hotel facade is going to look and it looks promising, can't wait to see what the finished product will be.
There's only valet parking here. Be sure to scan your ticket at the kiosk by the front door or have somebody help you scan it otherwise they might not know that you want your car. Calling in your car might not always work.
They also have cold bottles of water considering it's Phoenix and it's hot out.
The rooms are nice, the water pressure is FANTASTIC in the showers. There's a concierge lounge on the top floor so be sure to check that out if you have gold/platinum status.
