If you are looking for a convenient place to stay while in Rome then I highly recommend staying at Giacomo's place. First and foremost the check in process is extremely easy and allows for a lot of flexibility. This is something that was an issue with other places I had stayed in during my Italy trip so I must really highlight how great it is here.
The place itself is super elegant, modern, and has fantastic access to a private balcony. It was extremely clean and well maintained when we arrived.
Giacomo was very easy to reach and provided all the instructions ahead of time. He even offers a place to put your luggage before and after check in/check out which was very much appreciated.
I very highly recommend Giacomo's place. You will not be disappointed.
