Great location; I prayed for an apartment like this when I lived in Rome. Mirko is a wonderful host, explains everything clearly, and is ready to help you out in at any moment. You can text or email him and he has a great response time. My recommendation is to make sure you treat his space kindly, because he provides a lot of help to each person who stays here, and it would be good to show him your appreciation by treating it like it is your home.
