I 100% recommend this apartment!
Ivan is incredibly easy to communicate with and responds fast.
Checking in and out was very easy.
The apartment is tucked away off the busy city streets - it felt safe, secure, and like a quiet respite from a long day of site-seeing.
It is well located - walkable from the metro and train station, and also walkable to the Colosseum and Ancient Rome neighborhood. We found wonderful restaurants nearby and were able to cook various meals in the kitchen.
Beds were comfy, linens were great, and the neighbor even said hello in the mornings :)
