The place was real gem and I can't recommend it enough! It's the heart of Rome - however not very tourist-y - and walking distance to just about everywhere - nothing was more than 20 minutes away! Super close to many cafes, markets, stores, gelato places, etc. You literally can't wait 10 feet from the place without finding a small cafe or fruit market. The apt was very clean, had great A/C and wi fi and was perfect for our family of four. Two big TVs in each room (which shouldn't matter while being on vacain Italy, but after walking close to 13 miles in one day, sometimes, you just want to put your feet up and watch some Netflix. We also have two teenagers, so...... Nice little kitchen, but not meant for real cooking, but you're in Rome. Go out nightly and have a nice meal!
The bathroom is a little tiny, but it's Europe. so not surprising. Plenty of hot water and having the washer/dryer (in one!) was nice to have (note: it's not a quick process to do either, so plan accordingly if you do a load). The shower is maybe the tiniest ever and if you are at all a person on the larger side, it could be a problem. The one bathroom is also in the bedroom, which which was a bit inconvenient at times, but no big deal.
My girls said the sofa bed was very comfy. The apt is on the 3rd fl of the bldg (although we were told it's technically the 2nd since there are no units on the 1st, so just know this when you try to use the app to unlock the door and try for a while to get into someone else's place!).
Kelly was so great with her communications and graciously stored our luggage until our place was ready, which happened to be 3 hours ahead of normal check-in time. We had gotten into Rome that morning and were completely jet-lagged, so this was truly appreciated.
