Paola is a very nice person. This trip was my first with using Airbnb. And I think everyone should have like this experience for the first time.
Location is very good in Bergamo at Citta Alta if you like a place with history climate - you should choose this place. If you are searching for something like a modern/new fashion apartment - you shouldn't choose this place - leave this flat for people that will be feeling the house/flat/room :) It's easy to get to her place. But at night is harder to get a bus from Citta Alta to Citta Bassa. But it's isn't very far away and you can go on your feet or use Funicolare :)
The room is very nice looking and clean. Even that you are sharing a bath with Paola - you don't feel that. For me, that was the greatest thing (after meeting Paola) that even I felt I get my own place.
Summarizing: nice place, good location, great and open mind person. Yes, you should come to visit/meet - Paola and her place :)
