The hostel (this is not a hotel, though they also provide private rooms with attached bathrooms) is excellently located in close proximity to the Bergamo train station (only a short 10 min walk), and the central street in Citta Bassa where you can easily find restaurants and shops. If you wish, you could even walk to the Citta Alta funicular station in about 15 mins, passing by a pleasant neighbourhood on the way.
They also provide free breakfast, though that is nothing to scream about as it only consisted of some pastries, bread, milk, juice, coffee/tea and butter/marmalade. Still, it served its purpose.
Room and bathroom were clean, no complaints. My single room even came with a small balcony, though I did not use that as it was too cold.
