We stayed at Guglielmo's apartment and I would start by saying the apartment is very nice and very clean. The location is hard to beat as well. It is very close to the Vatican and it is on an awesome street with local restaurants. Also, the host left a couple bottles of wine for us to enjoy, which was very nice.
However, there were some drawbacks. Firstly, the listing stated the cleaning fee was included for stays over three nights and we were staying for three nights. However, the host repeatedly reached out asking us to leave some cash on the table for the cleaning fee. I ended up having to get Airbnb involved and was told that they would take care of it. But when we arrived I received another message from the host to leave cash. I had been told by Airbnb to never pay for anything outside of the site (except for tax), so we ended up not paying the cleaning fee. It just seemed a little unprofessional and sketchy.
Lastly, the listing says there is a washer/dryer, but the washer in the unit had a note on its saying not to use it. The note says to use the washer outside, but there are no directions as to where that washer is.
Overall, it was a pleasant stay, but I could have done without the hassle of the extra fees.
