Our plane was late in arriving to Rome. When we did finally get to the apartment we were met by a self-professed drunk host. He insisted that we pay multiple late fees, for our friend who was meeting us at the apartment before dinner, and for a taxi from the airport that we cancelled a half day prior when we found out we weren't going to make it on time. Not the best welcome after an extra 16 hours of travel.
Also, the wifi did not work the duration of our stay. It was one of the main reasons we choose this apartment, so that we could contact our kids and their babysitters overseas.
Third, the bar below the apartment was loud and made it hard to sleep.
