Check-in was difficult because we did not meet the host. We were meeting her assistant, but then looking for that person, we met someone else (another assistant). I think whoever we are meeting should be listed, and the one communicating with us. Also we weren't able to check in until later in the day and it took 45 minutes to go over how to get in and which keys went where, how to use the elevator, which doors to close and leave open, a contract, air conditioner, etc. Though the instruction was easy to understand its valuable time one doesn't want to spend while vacationing in Rome. Lastly, we had to leave the air conditioner on, but it still made no difference... apartment was uncomfortably hot.
