The apartement is located close to Rome Termini station and easily reachable on feet. It is surrounded by a nice residential area, however, getting slightly closer to the central station will reveal rather smelly and not clean corners of the city. The apartment had many good restaurants in reach as well as a supermarket that offered more than we needed. The connection to the city center is also very good and it takes about 30 minutes to any major sightseeing spot.
The inside of the apartement was as expected, very clean and had lots of dishes and tools, the bed was comfy and it was calm during the night. The only thing that bothered was a moving toilet lid, but besides I was very pleased with the whole interieur.
I think the apartement was nice and worth the price, I can recommend it :)
