I will write pros and cons.
Pros: The place is close to the train station. The pictures are exactly what the place looks like. It is a big space. Plenty of room for people to move around. There is a grocery store about 10 min. walk from the apartment. Hop on hop off bus is near the train station and worth it. Loved that the apartment has an elevator. Daniel is a wonderful host and responds quickly.
Cons: If you are tall, the shower heads are too low. The towels are rough. The coffee pots are small. You get maybe 2 cups out of the larger one but this seems what is the norm in Italy.
There are lots of hills in Rome so, if you plan on walking everywhere, you may want to stay someplace closer to the center of it all. Via del Corso area seems more in the middle. This apartment is more to the east. It is a great space and you have to decide what you want. If you take the train system or buses, you should be fine here.
