Upon our arrival we were not given clear instructions on where to meet the host to gain access to the apartment. We were left alone out on a busy and unsafe street surrounded by drug addicts and prostitutes late at night waiting for our host to show up. When he finally did show up he was angry and did not have the proper keys to let us in. This led him to going back outside yelling at someone while we waited and this made us even more scared and uneasy about the area. He quickly came back , showed us the apartment and then left, but did not give us a key to the main building so that we weren't able to leave to get anything to eat or leave until the next day. Before he left he demanded cash for a late fee. In the end we left the apartment because we felt unsafe and the host did not give us a key to get back in. We did not want to waste what little time we had in Rome waiting around for this irresponsible host to come back and give us a key. He did not call us until 12:30 pm the next day to give us a key but by that time we had already left the area. We felt incredibly unsafe .
