We found the route to enter this apartment CHARMING, you may not. We loved the low ceilings and the wood beams, but if you are taller than 5'9, you will not.
The apartment is in a fantastic location, not far from the Pantheon. A 15 minute walk to Trevi Fountain. And maybe 20 minutes to the Coliseum.
The rooms are decently sized. Length and width, but not height. The bed is firm but we like a firm mattress. The bedframe does try to punish your shins and knees if you walk too close. The kitchen had everything we needed, coffee pot, espresso machine with pods, kettle, microwave, sugar, dishes, etc...though we didn't use it much. The AC worked well but took a little time to figure out. The windows all open, but there are mosquitos waiting to come in, so use caution. (I honestly don't understand why screens are not a thing.) The wifi worked great. Water was hot, can get very very hot. Bathroom had modern amenities, but was a bit tight.
We also appreciated the thoughtful touches, detergent for the washer and a sewing kit in the bathroom, just to name a few...
The host, Flora, was very communicative with us prior to arrival. Helped us get our luggage to the apartment. And showed us how everything worked. She was swift and thorough. She was friendly and answered all of our questions, but didn't linger.
Like I said, we were charmed by the apartment, but if you have any mobility issues, this will not be the place for you. You go up a spiral staircase, through a little hobbit-sized door, across a flat roof-top, and then down more steps to your front door and patio. So does your luggage.
We would absolutely rent it again, but we would pack lighter.
