All in all we enjoyed our holiday in the apartments (we had two apartments from Em Properties in the same house). The location was too far from Bergamo town without own transportation, but if we'd had that sorted, it would have been perfect for our family of five plus two people in the smaller flat.
The apartment itself was spacious, clean and nice.
At first getting contact to Emily was easy. We had some issues though during our stay and when I reached to her I haven't had any answer back for a week now.
If I wanted to see Bergamo for a week this would not be my first choice (at least without a car), but if I planned a longer stay or wanted to travel by car around northern Italy this would be a good choice to have as "headquarters".
Btw, it is good to know that taxi service is hard to get in Bergamo and the airport. We couldn't get a taxi without help and with local help it took hours (no kidding). We tried different local taxi services. Maybe we were just unlucky, but this is useful to know if you're planning to compensate the location by using taxis.
