Vicolo Delle Grotte was perfect for our first stay in Rome. And Ariele was the perfect host. Ariele was very accommodating when it came to check-in time and was at the apartment at the specified time. He helped to carry our bags up to the apartment and gave us a run through of the place. He also helped with logistics of our sightseeing by providing a map and some pointers and telling us where to head for dinner that evening. He was at the other end of the phone at any point during our stay if we needed (we didn't). Because there were no guests arriving after us our check out time was very relaxed but nevertheless Ariele offered to store our bags at his friends shop if there were infact going to be guests arriving. He even arranged a taxi for us which was handy and ensures we had an honest taxi driver offering the fixed airport transfer fee.
The apartment was in a good central location within walking distance of everything (we didn't get a taxi/bus/metro once). It was clean and had everything we expected from it after reading the listing originally.
Thanks for making our stay in Roma comfortable.
