Very clean and well kept. I will say there’s no vending machines so if you need beverages or snacks get them before hand. Stores and restaurants are within walking distance which is very nice. The staff was nice and checking in and out was very quick.

Great for a simple overnight trip. Check in and check out was quick, the front desk staff was readily available to help, and the room was very clean (probably the most important thing). Comfortable beds, and 24/7 coffee service. It doesn't have anything extra (no breakfast or pool) or fancy (basic amenities- but very comfortable and more than sufficient), but it was perfect for what we needed. If you are looking for a quick stay someplace that is very clean and comfortable and the staff is helpful and polite, we recommend it and would return again.
