This is perfect apartment for two people located right next to the funicular from the lower town. Very well renovated everything you need is in the apartment. Sparkingly clean as well.
Although it did not spoil our time in Bergamo, the apartment is located above the "Best Irish Bar in Bergamo," and there's a bit of noise from that till 2 am. Only mentioning it in case you are a light sleeper, but to be clear it has not prevented us giving the apartment five stars and to repeat it did not spoil our weekend in any way.
Handy tip, when you arrive at the airport go to the tourist information and buy the 7 Euro 72 hour transport pass. This allows you to use both funiculars and all of the buses including the airport shuttle bus.
