We just returned from a 2wk vacation from Italy and Greece. Rome was our first stop, we spent 4 nights at Carla's Casa Roma, we couldn't be happier with the apartment, it had definitely set a high bar for the rest of the trip. Here are the few highlights:

Location: Very central and convenient, Trevi Fountain, Pantheon, Capitoline Museum, Colosseum, and the Spanish steps are all within 5~10 mins walk. We even walked to Campo De Fiori and Piazza Navona just to explore the city. For farther attractions, the H line bus is right around the corner that will take you to Trastevere and the Termini. The Republica Metro stop is 5 mins down Nationale.

With the proximity to the attractions, the immediate neighborhood is very quiet and non-touristy, has plenty of good restaurants, and a mini mart right next door.

The Facility: We love the apartment, with the new upgrades, the bath room and bedroom feel very luxurious, and BIG, especially by European standard. The living room and kitchen is a little smaller, but very adequate (hey we are in Rome, last thing we want to do is to spend too much time sitting around and cooking:-)

The Host: Carla has been great before, during, and after our stay. Very prompt in answering any questions I have. Even printed a guide to help find anything you need around and beyond her place.

I was having some difficulty operating the wash machine (total user error), I emailed her, she got back to me quickly and have her boyfriend come in to help. Not just that, but they reached out to make sure it's ok to enter the apartment in case we are out, that's exceptional courtesy.

I will stay at Casa Roma next time in Rome if it has not become to popular and hard to book:-)
