I highly recommend this apartment. It is in a terrific location, very central and easy to access pretty much all the essential areas of the city. It’s near bus and metro, and in easy walking distance of the Trevi Fountain and surrounding area.
The apartment itself is very clean and modern, pretty well equipped. Note there is no washing machine. We did a bit of hand washing but I suspect the hotel (the apartment is run from the boutique hotel literally around the corner of the same building) would arrange laundry if you are staying longer.
The air con was not working when we arrived and it was HOT. I was concerned about this but need not have been-I messaged Katya and her staff and they immediately set out to solve the issue. We decided to go out for our first evening in Rome and when we came back it was fixed and the apartment was a wonderful temperature. No further problems arose with the air con during our stay.
I was very impressed with the way this was handled.
In summary, I would recommend this apartment highly and would stay again if I come back to Rome. My whole party felt the same.
