Overall okay for the price.
The location is what sold this for us. It's only 10 minutes from the Colosseum and has multiple great supermarkets less than 5 minutes away.
The flat is in a classic Roman apartment house with a nice entrance. The furniture and decoration is very classic Italian. It however feels a bit empty in a way - like no one actually lives there. If you want a real home AirBnb take this into account. It has the basic essentials to make dinner but I would recommend this flat If you mostly plan on eating at restaurants because the toaster didn't work, it only has salt and pepper and sunflower oil (the olive oil bottle cap was open and there was only a drip left) and no wine glasses. There was also no hand soap which was a bit bizzare for us. We had to use tiny shampoo samples for hand soap in the bathroom and kitchen (we were given just enough of those bottles for our 5 days).
It's great that the flat has a washing machine.
The complex looks nice and has a view from the window to the inside of the courtyard so it had an authentic feel to it. Neighbors were nice but unfortunately when we were there, there was a party every single night upstairs with people singing and dogs barking til 2-3am. Luckily we could sleep ok but maybe it's something to take into consideration if you're a very light sleeper.
The apartment was not very clean. The bed was nice but the cookware and floors were not very clean. The sofas have stains on them and so they weren't perfectly comfortable to sit on but it becomes bearable after a few glasses of wine. The ventilation in the bathroom was very dusty.
It wasn't clear where to put the trash, because there was one small trash bag in the bin in the bathroom but nowhere else.
Our communication with the host was minimal. He wrote us saying our host would be someone else. Turned out the next host couldn't check us in either so a third host checked us in who isn't named in the listing. His English was not very good so it helps if you speak italian and an advanced level.
