My wife and I stayed at the apartment for 5 days during our recent trip to Italy. Monica was very responsive to our inquiries and met us at the apartment when we arrived.
Apartment was well equipped and as described.
Location was great, you could see the Coliseum as soon as you walked out the door and it was about 5 minutes to the subway.
Good restaurants nearby and a couple supermarkets.
Only issue we had was the air conditioner was effective for the main floor but it was still warm in the loft area. There is a fan in the loft to use of you can sleep on the futon.
Either way, the experience was great and I would recommend staying here while in Rome.
