The apartment is spacious enough for 4 adults, each room has a comfy bed with AC and a window. There are plenty of entry doors to the building making it very safe.. The location is EXCELLENT. You are a few meters from the Cavour metro station - that easily connects you to the central Termini station, and so close to the Colosseum; you can walk, there. The neighborhood has so many restaurant, mini markets and bars around making it hard to leave Monti. As noted, the apartment is located in the 4th floors, so come prepared to climd stairs. There are a few areas of improvement, in the bathroom specifically, that can be made and those have been shared with the host (finding a solution for the sewer smells that often comes and making sure they sanitize, clean and ventilate the bathroom correctly.)
Overall, great, spacious apartment. Good communication with the host and the managers. They offer airport transfer if you want to check pricing. And the apartment has washer and dryer.
