The location of the property is perfect, not only almost all major sights are within walking distance, the cobble-stoned street itself is also home to some fantastic eateries - Le Baffeto Pizza, Frigidarium, Fattoincasa, ... all just a few steps away, all popular with locals with long lines all night, all open well past midnight, all unforgettably good.
The apartment itself is clean and comfortable, the quietness is surprising, given its proximity to everything touristy. The apartment sleeps 6 easily, everything just works.
Of course any review wouldn't be complete without good words for the host. Andreas is about as perfect as there is - from pre-trip communications, to airport pickup arrangement, to arrival greetings and introductions - he's a great communicator, flexible, knowledgeable, and goes out of his way to help out.
In all, Andreas and his apartment is one of the main reasons why we already want to come back to Rome for more. I will recommend him to all my friends needing a great place to stay in Rome.
Thanks!
