This is a great place to stay. It is just as beautiful as it is on the pictures. The apartment is very tastefully furnished, has a comfortable chair, an excellent mattress on the bed, a useful desk and table. The kitchen is small; it's possible to cook a simple pasta but not much more (there are pans, for example, but no lids). The air-conditioning is an wonderful addition - it was very welcome during the heat of August, particularly at night it brought comfort.
The location is fantastic - it's right on the Via Galliera, one of the oldest and most beautiful streets of Bologna, and it's very central.
The check-in was efficient but rather quick (except where Andrea told enthusiastically about the movies shown in Piazza Maggiore during summer); I realized later that I hadn't been told, for example, how the washing machine works or what to do with the garbage (which are relevant for someone staying for a longer period). Monella did respond quickly to email requests to provide the relevant information.
