The apartment is in a wonderful location - it's not too touristy and the streets are atmospheric, while still being easily in walking distance from the centre. There is a lovely square nearby with bars, a church and a fountain, but without the hoards of tourists and their selfie sticks that swarm in Rome's bigger squares.
The studio itself is perfect for a short break: it was nicely furnished and clean. It's more like a modern hotel room with an added stove and fridge, so great if you're going to be out all day sightseeing. The shower is good and we had no problems finding the address or being let in.
