Absolutely amazing! If I could give bonus stars, I would.
The decoration and feel of the apartment makes you feel absolutely submerged in Italian culture, and the location is amazing, giving you a private and safe feeling while still being in an amazing location. 10 Minute walk to Trevi Fountain, 15 minute walk to the Colosseum, and tons of amazing restaurants and stores very nearby.
We really appreciated how clearly we were told everything in the apartment worked, we had absolutely no confusion or worry using anything.
I 100% recommend booking this apartment if you are able to, I have never been happier with a stay in an AirBnb.
