A good deal. I asked for ground floor but he said they were all booked up but didn’t check the computer and put me on the third floor. I had booked weeks in advance. $60 cash deposit required. Never experienced that before. Comfortable place and a good value.

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!
