We truly enjoyed our stay. The location is perfect, just in Campo di Fiori, close to all important sites in the city. You can easily access the appartment with car so no need to carry your luggage from where the taxi drops you off. The appartment is nice and spacious and the building even has an elevator (but a tiny one!!!). The only thing that was missing is light. The main living room was lighted with a very poor light so it gave us a bit a sense of underground place but it was really minor thing.
I truly recommend on that listing!!!
