Emidio is a gracious and responsive host, who goes out of his way to answer any and all queries.
The apartment is located steps away from a metro, and only two stops away from the Vatican, 5 stops from Piazza Populo. There is a small supermarket in the same building, which is very handy for odds and sods. The neighbourhood is peppered with cafes and local restaurants...note they do close in the PM (like most of Italy) so plan accordingly.
The apartment itself is well laid out, comfortable and very nicely furnished. Numerous nice touches abound (capsule espresso machine, for e.g.) and everything is crisp and clean.
When we were there, there was a quirky situation with the hot water supply, an issue I am sure Emidio will address, as he is very fussy about things working as they should.
A definite recommend, and we would happily stay at Emidio's if we were to visit Rome again.
