Patrizio's place is not particularly spacious or luxurious - however the dimensions are in the listing and the place is clean and secure with a good bathroom (great shower) and a comfortable bed. There are three locked doors before the apartment so we felt very safe. It's in a great location too - easy walk to many key attractions and just around the corner from a lovely restaurant called La Caveau - I'd recommend a visit!
I've recommended Patrizio review his listing as at the time of writing there are a few things on there that are not available in the apartment such as TV and coffee maker (I was particularly disappointed by the lack of coffee maker!!). There are pots and pans but no implements to cook with so you'd struggle to cook a meal. There is a stove top whistling kettle but we didn't use it. I didn't notice an iron or hair dryer but these may have been in the wardrobe - we didn't use it. The listing also suggests there's a patio or balcony and this is not the case either.
However, as I said before - it's in a good location, it's clean and secure and for the price I think it's great for what you need - I certainly didn't come to Rome to sit in my apartment for long periods so this is fine!! Patrizio was responsive and helpful too. Thanks Patrizio :)
