This is hands down the best location for eating/partying/exploring the city. You are a stones throw away from all nightlife but far enough to where you can't hear the drunken mess. You are central to the coliseum, the Spanish steps, pantheon, and trevi fountain.
The best food in Rome is always a little out of the city, but Antonios apartment is only a 5 euro taxi to the best of the best.
Anthony is the man, always responded timely and had some great recommendations for us!
