Bologna Red is a superb place to stay in Bologna. We liked it and we recommend it!! We were in Bologna four nights in Easter.
It is very clean, there are all you need and most important, it is in great location.
Refrigerator is good, there is a espresso machine, washing mashing etc. If you want to make food by yourself, pan, kettle etc are in good condition.
The flat is in an old building. It is a quiet and beautiful place. You might hear church bell sometime, but this did not bother us at all. You can see the church in the kitchen window.
There are some steps to go to the place, so I recommend not to carry one big suitcase, like we did, but rather two smaller ones.
