We had a very pleasant stay at Marcella's. There was plenty of space for three families (6 adults + 4 kids) and we found it very convenient that each of the three rooms has its own bathroom.
The location is really good to visit Bergamo on foot or explore the hills around, yet it is in a very quiet and peaceful placement.
The host was very kind and welcoming and he came to guide us on the way to the house, which is a bit tricky if you arrive at night as it goes through a narrow passage between other houses. I would not recommend driving there with a van or a very big car but otherwise there is parking space right below the house.
We found a fully equipped kitchen and everything you could need for cooking. The rooms are heated and even in December it felt warm and cozy. The whole house was clean and tidy and the newly renovated bathrooms contained hair dryers and all needed toiletries.
Overall a very recommendable choice.
