Rita and her family were amazing hosts, we enjoyed our stay near the old town, which is also very close to the bus stop (cca 50-100 m) and not so far from bikesharing point (cca 250 m), so you are close to almost every kind of transportation to enjoy the whole city.
Place was tidy and they prepared few wines and juices (with prize on them) so you can "buy" it when you need it and you don't have to go to the groceries (speaking of groceries, little shop is few steps away so it's very easy to obtain fresh things in the morning). They prepared for us few things as nutella, cookies and marmalade for free.
Communication was on good level so when we needed something from Rita, we got our answer in few minutes.
At Rita's you can find also a little box where you can place your suggestions how to improve their hosting. It's a nice touch and throughout this idea they try to be as close as possible to their guests. For me, this is one of the reasons why Ritas place is great choice for your stay in Bergamo.
