Domenico was the consummate host (and he loves jazz!). But for my husband and I, he went above and beyond. Two days prior to our arrival in Rome, my husband sustained a knee injury that limited his mobility substantially. Domenico and I had already arranged that he pick us up at Termini, so that worked out well. A couple days later, the knee problem got worse, and we decided that crutches were needed. Domenico picked me up and drove me clear across Rome to an orthopedic farmacia to purchase a pair of crutches, and then back to Trastevere. He could not have been nicer about it, and we are forever grateful.
As for the apartment: it's perfect for two people who want to explore this fascinating part of Rome. The food, the nightlife, the shopping. It's all there, without the "big city" feel that Rome has across the river. But it's also so well located, that getting to all the major tourist destinations is not a problem, even on foot. (I walked from the apartment to Vatican City, to Piazza Navona, to the Pantheon and back in about six hours; taking my time, of course, and visiting several artistically interesting sites and churches along the way. Oh, and had a very nice lunch at an off-the-trail restaurant near Piazza Navona. All that said, there is a taxi stand just a block away near Piazza Trilussa.)
Artevere was the perfect coda to our two week trip in Italy, and when we return to Rome, we will definitely book it again.

PS: Bonus, being directly above La Renella!
PPS: That shower is amazing!
