We had a wonderful 3 night stay. The apartment is beautiful and elegantly decorated and clean inside! The location is convenient for walking to all sights— albeit insanely busy— but Trevi fountain, what can you expect?
The elevator broke on our arrival which was a bummer with our heavy months worth family of four luggage. But the owners assisted as much as possible and the lift was fixed within 48 hrs!
All around super positive stay. Be aware of some street noise, but nothing too disturbing.
