Tatiana is a truly helpful host, who is very responsive and gives travel tips freely.
The apartment is located within comfortable (for us, 20 minutes) walking distance to many of the major attractions. Within the 2.5 days we were in Rome, we were able to visit so many of them, including the Colosseum and archeological park and the Vatican Museum and Sistine Chapel and others. There are a number of piazzas, both large and bustling as well as small and more peaceful, nearby. It seems to be in a fairly popular tourist area (we heard a number of different languages spoken by folks on the street, with English being predominant) on a smaller street that has a good amount of pedestrians and an occasional vehicle passing by. That being written, there wasn't a lot of noise at night, and we were able to sleep comfortably. There is a Carre Four Express a few steps away, so we were able to do groceries whenever we needed.
The apartment is on the first floor, and we could get to and from the apartment using the stairs easily. There's an elevator, too.
The kitchen was well equipped to do most types of cooking that we do, and the essentials (towels, sheets, etc.) were well-provided. The laundry machine and dryer are in a separate room, so we weren't disturbed when we ran either of them at night.
The ceilings and the door frames seem to be original details, which we appreciated. The apartment is a unique layout. The main space has a bedroom area and a living room/dining/kitchen space, separated by an open shelving unit. The kitchen island sits 5 comfortably and could fit 6 in a pinch. There is a separate bedroom, through which one can get to a small, open loft with a single bed.
One thing to think about is privacy. Our family of 5 had no real issues (we had 1 kid in the "bedroom," 1 in the living area's convertible couch, and 1 in the single bed in the loft above me and my husband in the bedroom), but other travelers might. Also, the only bathroom is accessible through the bedroom. Again, this wasn't an issue for us, but it might not be ideal for a travel group with a different dynamic.
Overall, a lovely stay in Rome, thanks to Tatiana and her apartment!
