Mario was so welcoming. He met us outside just as our taxi pulled up, and showed us the apartment. Couldn't have been more pleasant, and was always prompt with communication and help when we needed (for example) to figure out how to work the TV.
Apartment very elegant and clean, and firm bed very comfortable. We slept well! Sofa, not so comfortable, but maybe that was just me. Kitchen well-equipped and easy to work in. Couldn't figure out the microwave, but I'm sure Mario would have been happy to show me if I'd asked. Only real inconvenience was that wifi only worked in the bedroom, but again, that might not be a problem for some.
In all, we had a lovely time in Rome, and self safe, cozy, and at home in Mario's apartment. The location is truly magical.
