The apartment was great! The apartment looks just like the pictures and there was a bottle of prosecco waiting there for us. We had to grab the keys from the restaurant across the street (Divin Ostilia) since Andrea had a last minute business trip but everything was communicated and went smoothly. The locks on the door are insane and awesome (a little tricky to figure out but eventually we got it). I felt super safe in the neighborhood. I recommend locking the door when you are in the apartment just so you don't forget the keys- I never felt unsafe, I just worried about forgetting the keys. The bed seems very new but it was extremely firm (not great for this pregnant side sleeper but it worked). The bedding was clean- we were actually very warm in January and had to turn off all of the heaters. The shower door was a weird accordion but it worked- heads up the shower was a little short for my 6'4" husband but he made it work. Towels were there. The downstairs bathroom had a leak but Andrea took care of it the next day with his housekeeper so we didn't have to worry about a thing. Glasses and a bottle opener were the only thing we used in the kitchen- there is more but we ended up eating out more than expected.
Speaking of food, I recommend eating at Divin Ostilia (we did twice). The neighborhood is full of great food (seriously, every block has more than one option). Another great option: Pizzeria Luzzi (we ate there multiple times & locals eat there). You can see the Colosseum if you stick your head out the window and right across the street is another, less familiar piece of the Colosseum (the gladiator "housing" and training side). We took a taxi from the airport and used Uber once we got there for our trip to the Vatican and back to the airport. WiFi in the apartment worked great and could work from the street while we waited for our ride. Everything else we did was in walking distance. I highly recommend a bike tour. The price and location of this place still amaze me and I would go back there again! Andrea is a great host and while I have only stayed at one of his properties, I would have no doubt about recommending any of them.
