There were pros and cons to this apartment:
Pros:
-Located in a great, lively area, but off the main street so it's fairly quiet at night.
- Has air conditioning, which is nice to have in Rome sometimes.
- A pretty good amount of room for 2 people (though I don't understand how the listing claims 4, as the couch does not look big enough for 2 to me)
- Owner set up a private cab from the train station for us (note though, private cab was 40e, when we took an Uber back at the end of the trip, it was 14. He did warn me it would be expensive though)

Cons:
- When I first tried to contact the owner a little more than a week before arriving to confirm the reservation and establish arrival details they did not respond to my first several emails and phone call over several days and it was only after I called again and actually got somebody on the phone 2 days before arrival that they actually started responding. This caused me a lot of unnecessary stress on the first leg my vacation. I would note here that the property is managed by Andrea's employees as far as I can tell, I don't think Andrea is actually the person you're talking to over email.
- The apartment did not seem fully ready to receive guests. There was only 1 roll of toilet paper (for 2 people for almost a week), almost half the light bulbs were burned out, and the washing machine door would not open - eventually I figured out you have to jam a knife or spoon into the spot the handle used to be to get the door open, and one of the light fixtures has to be plugged in behind the couch to turn it on, but even when I emailed to ask, nobody ever explained any of this to me. Even when we got the washing machine working it doesn't work properly so I had to advance the cycles manually or it would run forever. They did eventually bring some more TP when I asked, but they never fixed the burned out lights or the washing machine.
- The woman who works downstairs, while very friendly and helpful, also smokes cigarettes continuously every day from around 4 or 5pm until 7 or 8 while she's there. This means if you don't want the apartment to smell like cigarettes you have to keep all the windows closed all evening. You also cannot dry your clothes outside or they will also smell of cigarettes.

All the problems I've noted were all fairly minor things individually, but adding them all up I think next time we come to Rome we'd probably choose a different spot. Most are easily addressable though, so hopefully the owner makes some steps to do that.
