This is a nice place for sure, but it is a little misadvertised. I'm going to focus on the bad just because I think it's more useful to readers, but if I don't mention it here you can assume that it's fine. The balcony is very tiny and my fiance and I could barely fit on it, in addition the table is attached to the wall and broken, so it cannot be used and you cannot remove it and put a different table out there, so the balcony isn't much of an option. The balcony view is decent but also is just into a complex of other apartments as opposed to a road or anything. There are very few cooking implements so it is hard to make a meal for yourself. The wifi was manageable but not great. The best thing about this place is the location, hard to beat as it's right next to the pantheon and within walking distance of trevi fountain / spanish steps / etc. That being said it is a cute place, and has a good amount of space, comfy bed, and decent bathroom.
My biggest problem was check-in was horrible. We were told to go to a bar to retrieve our keys, and I don't speak Italian so it was difficult to communicate that I was looking for an Airbnb key. Eventually they understood but said they didn't have my specific key, so I waited at the bar for 30 minutes with all my luggage for the host to come and give me them. It was a pretty good response time by the host so I appreciate that but still, they need to improve the check-in process.
