The location of the apartment cannot be beat. Just steps away from Campo di Fiori where you can get fresh fruit and vegetables throughout the day. Easy walk to the Vatican, Piazza Navona, and all the sites. Event the Coloseum is an easy walk (about a mile), if its not too hot. And the terrace is really spectacular. Amazing view of Rome. Great spot to have breakfast and sip a glass of wine at the end of the day.
As others have mentioned, there are a lot of steps--it is on the 5th floor (that rooftop view exacts a price :) ). One other small downside is that because its an attic apartment, the roofs slant, so you will bump your head if you're not careful. Otherwise things were really good. I had to take some Zoom calls, and the wifi worked great for that. The air conditioning was good, and refreshing. The kitchen was small, but well stocked (including a Nespresso machine to feed my coffee habit). I would stay again!
