First: Alexandra was a great communicator, and was able and willing to help accommodate me with an early luggage drop off. Not having to lug my stuff around the conference venue was a fantastic bonus.
Second: the location is amazing! It's really in the heart of stuff and I believe, depending on what floor of the Hilton you were staying on, you might actually be able to get to John's place quicker from the Hilton Lobby. Great business value for the location, no question.
Third: the space was cool and clean. Photos are accurate, and everything functions properly. They even had some coffee available, which was a nice touch. Chomecast on the TV was also a nice bonus for winding down in the evenings. The shower knob took me a bit to figure out, haha (TIP: the middle ring is for heat control, the outer lever is for which "device" you want - tub, showerhead 1, showerhead 2, both at once), but once I got it down it was simple enough.
Fourth: there are only a couple "issues" I had with this stay. 1.) The tenants upstairs weren't ever overly loud, but there was some undeniable noise at odd hours in the evening/early morning, and 2.) the fan for the HVAC is LOUD. When it kicks on, you'll notice it, and it runs for a bit (weather depending, I'm sure). It woke me up a couple times when it kicked on in the early morning, since it's located pretty close to the main bed. If you're a light sleeper, this is worth noting. They did have a container of ear plugs on the counter, so that was cool, but I can't wear ear plugs while I sleep, so that's on me, I suppose.
I'd absolutely stay here again; the tenant and fan noise weren't nearly enough to keep this from being a great stay.
