The location was excellent. The Colosseum was right outside our front door. All of our main sights were walking distance (under 2 miles). There is also a Taxi Stand outside the front door if you need to have shorter walks. The Apartment was not modern, but that is not what we were looking for. It was nice and completely worth the money spent.
The only negatives were: 1. The communication was tricky at first. I called two phone numbers upon arrival, but neither person spoke english. It left me a little frustrated, but shortly after a third person called me and spoke english. It took the third person about 15 minute to come let us in. After that, all was well. 2. There are a lot of stairs. We consider ourselves walkers so it wasn't a huge deal but, if you are adverse to stair climbing, this may not be for you.
