The apartment is at a good location in Roma Sur. There are plenty of places to eat and shop within walking distance. The building was relatively quiet during our stay.
It's on the ground floor so there there no stairs to climb. The windows all look into a private courtyard in the middle of the building (nothing fancy, just a place for water storage tanks), so there are no issues with people walking around outside or street noise.
The apartment has all the basics you should need for a place to sleep, shower, and relax. The kitchen is pretty minimally equipped (we did not use it much) so I wouldn't plan on making any big fancy meals. There are so many cheap and easy dining options in the area, you should not really need it.
The adjacent streets have relatively low traffic. It was easy to get picked up/dropped off at the building. We had a rental car for part of our stay and did not have any trouble finding street parking near the building.
The aspects we enjoyed the most were the decor, comfort, and location.
