Problem Solved! When we arrived at our Airbnb we were told there was a problem because the apartment had not been cleaned and cleaning services could not come. However, we had the option of staying in a different Airbnb operated by the same owners. The substitute apartment was much smaller than the one we reserved, but had a rooftop terrace. So indoor + outdoor space was about the same as the indoor space of the one we had reserved. The location of the substitute was actually much better than the one we reserved. It was a 2-3 minute walk from the Spanish Steps and, therefore, close to many historical sites. We appreciated being offered a good option, and we loved the location and terrace!
