Dario was very helpful and responsive from the very early stages of the booking (about a month before our arrival). His responses on the whole variety of questions (including the transportation and sightseeing in Rome) were almost always instantaneous and very detailed. Dario's apartment was very clean and new. All appliances were functioning flawlessly, we really enjoyed the shower which was really high quality. Although we haven't met Dario, he was omnipresent during our stay. Upon a slightest need he would come and fix a defect, should it arise. He did great job leaving very elaborate "handbook" describing how to use the AC, safe, etc, how to get to the center of Rome at night, etc. The only drawback is that it's not the very center of Rome, and if you are not opposing using metro (sometimes with some connections) then it's a great apartment and great host!
