There's a lot to break down here. I'll take it point by point:
Incidentals/Move-in
Bluegrounds provides a variety of items necessary to clean and manage your apartment life, potentially saving you a trip to the store and allowing you to settle in with relative ease. It's nice to be able to wash your clothes and take a shower right after moving in. This helped ease my spirits after going through the check-in process. Despite intimations to the contrary from Bluegrounds, the front desk was not clued into the process at all, which involved picking up the digital apartment key from a lockbox in the adjoining alley. Water might be tight at first, especially if there's more than one in your party. Bluegrounds provided only a single water bottle, and the water from the tap tastes like mud. One of my first purchases after moving in was a water filter.
Facilities
While most of the building interior, the halls and elevators, seemed decidedly run down, the lounge and gym were modern and reasonably well-appointed. The apartment itself was white painted concrete with ceiling pipes visible, but I didn't find it uncomfortable. The mattress was decent, the bathroom was nice, and the washer/dryer was efficient. The kitchen had everything I needed and a lot of stuff I didn't. One negative about the appliances was that every one seemed to be rigged to make a loud beeping noise, which echoed annoyingly off the walls. The wifi didn't work when I entered the apartment, but was fixed afterward, more on that later. Once it did work, it was good for most purposes, a little slow for large downloads if you're used to high bandwidth. Given the location right next to the train you might expect it to be noisy, but I found the apartment well-insulated from most sounds. You could still hear the train and some street noise, but these were at bearable volumes. Slightly more annoying were the occasional barks from dogs inside the building. All-in-all, I found nothing more annoying than the technically self-inflicted beeps from appliances, and nothing else too much louder than the air conditioning. The listing advertises itself as a perfect place to work, but I found furniture to be an issue. I ended up co-opting the dining table to work on, and used the large, low coffee table to eat my meals, which wasn't ideal.
Bluegrounds, the host company
Bluegrounds tried very hard to give an image of caring about my stay without putting in any actual work. As I said, when I moved in, the wifi didn't work. This was eventually fixed, though I'm not sure if it would have been if I hadn't pointed out that this made the Airbnb listing materially inaccurate and gotten Airbnb involved. During the point at which I was trying to resolve this issue, I got only sporadic contact from Bluegrounds on it, and at the same time, received other communications telling me that they hoped that my move-in was going smoothly. The only genuinely positive interaction that I had with Bluegrounds was the care they took in providing the move-in incidentals. The goodwill I had towards them due to this gesture evaporated when they attempted to charge me on moving out, effectively allowing them to bill it forward. The mostly benign neglect is about what I would expect from any small-time landlord.
Overview
All-in-all, having given all my caveats above, I can cautiously recommend the experience. You're paying almost as much as you would for a hotel, but don't expect a level of service even approaching that (or anything, really). Instead, you're getting a decent apartment in the Loop.
