Very clean and pleasant space and a convenient walk to the metro. However, it can be hard to find at first for people without data access as it is in the middle of the street.
Also, I received a rather rude message from the host about the air conditioning use, which he did not specify and explain (although we adhered to the house rules and he later commented it may have been a misunderstanding), which left a bad taste during my time in Rome. Otherwise, he was kind and explained things well for us.
