My husband and I stayed at this apartment at the beginning of October. We were met by Emanuela's assistant, Mauro, who was very friendly, helpful and kind to us - took me to buy bus tickets and pulled my heavy suitcase!
Emanuela herself was very communicative and accommodating, providing clear instructions on how to get to her and other helpful tips.
The place is incredibly central - the trevi fountain is literally 2 minutes walk away and this worked well for me taking afternoon breaks from sightseeing.
Great Wifi!
Fairly quiet at night, though garbage men some mornings - not for light sleepers.
There were plates, salad bowls, mugs, dishes, olive oil, salt and pots (no kettle) and even limoncello if I recall correctly.
Other comments/tips
Place is a little dark and stuffy and the AC is loud. We weren't too hot as we slept with the fan (used the AC to cool down during the day) and summer was over anyway
I advise you to bring your own shampoo/soap and Kleenex
If you are sensitive to crowds of people, like I am, then maybe consider staying somewhere less central (though as I said, it is quiet at night)
San Crispino is in the street parallel - get some anise gelato!!
