Let me start by saying, yes, I would recommend the apartment. Overall we had a great stay. There were four of us (two couples) who stayed three nights in June. This is a very clean apartment with plenty of bedroom space and two bathrooms, a huge plus for us. It also has an elevator, something not to be taken for granted when you're traveling with suitcases. The location was terrific, although a bit close to the train station. Why should this be a problem, you ask? Because train station neighborhoods in Europe tend to be a little questionable, and Rome is no exception. We walked from the train to the apartment, through areas of debris and puddles that smelled like urine. Again, if you've traveled Europe, this is not all that unusual in the main train station neighborhoods and I never felt unsafe. This apartment is on the fringes of the run-down neighborhood and there were some sketchy characters who hung out on the steps of the building across the street, sometimes breaking bottles and fighting with each other. This made my traveling companions a little uneasy but having lived in Europe for a while it wasn't as disconcerting for me.
The only other minor complaint we had was the air conditioning. To be fair, I will say that we visited during a record heat wave, but the small units in the bedrooms struggled to cool the bedrooms at night. We turned them off during the day when we were out, as the hosts requested, and the rest of the apartment is not air conditioned but there are a lot of nice big windows.. The bedrooms are spacious, with high ceilings, so these small AC units seemed pretty underpowered. We also had some difficulty getting one of the units to come on at all, although my husband was able to keep at it and make it work.
