Unfortunately we did not have a great stay and had to leave due to broken air conditioning. I think had the a/c been working we would have had a very nice stay at Angelo's apartment. It is a lovely place in a great location very close to Piazza Navona. But for us with Rome being quite warm in July we needed a place where we could sleep well and had to vacate the apartment after the first night.
I was a little disappointed in how the situation was handled initially as I called the "main office" of the group that owns these Airbnbs and informed them about the a/c problem right away and they said someone would be sent over. However after a while no one came and I contacted Angelo who told me that someone would be able to bring over a fan tomorrow. We ended up spending a sweaty and sleepless night in the apartment before we headed out for the next day of sightseeing.
It was not until I became a little more aggressive that things started happening. Angelo was reasonable when I wanted to leave and requested a refund and understood our frustrations so to that end I give him credit. It was a Sunday so I'm sure it as hard to find someone to fix the a/c that day.
A few other minor things that could be addressed- the check-in is at a luggage storage office about 5 mins walk - it would have been nice to have someone walk us over to the apartment as it is a bit hard to find hidden in the back streets near the piazza.
