Disappointingly Incomplete "Kitchenette" - Spartan Stay I recently stayed at this hotel specifically because the "kitchenette" feature was important for my needs. Unfortunately, my stay was a significant letdown. The most frustrating aspect was the so-called kitchenette. While it included a refrigerator, stovetop, and microwave, it was completely devoid of any utensils. There were no pots, pans, plates, cups, or cutlery. Most surprisingly, there wasn't even a coffee maker or a simple water kettle to boil water. For a hotel branded as "Extended Stay," this renders the kitchenette utterly useless unless you travel with a full set of your own cookware, which defeats the entire purpose. The accommodations were exceptionally spartan. The room was clean on a basic level but felt bare-bones and dated. The overall impression was one of a place that provides the absolute minimum required, with no effort made toward comfort or convenience. While the staff I interacted with were polite, the fundamental shortcomings of the room's amenities overshadowed this. For the price point, I expected a functional living space, not an empty room with appliances that can't be used. I cannot recommend this property to anyone who actually needs a kitchenette. You would be better off at a standard hotel room or look for a more fully-equipped alternative.

The room was really quiet and clean. I liked the fitness center a lot. They have a coffee shop in the lobby, which was great.

I recently stayed at Studio 6 and had a pretty pleasant experience. The staff was fantastic — very friendly and accommodating, which made checking in and out a breeze. The room was spacious, clean, and comfortable, though it wasn't perfect. The size of the room was definitely a highlight, giving plenty of space to relax after a day out. While the cleanliness was good overall, there were a few minor details that could’ve been better, but nothing major to complain about. The location is definitely a big plus too! It’s in a quiet area, but still just a short walk to the convention center, which made it super convenient for my trip. Overall, it's a great spot for anyone needing a clean, comfortable place to stay with easy access to the convention center and other local spots. Definitely recommend if you’re looking for something affordable yet reliable!
