This studio is in the most gorgeous location, on a pedestrianised road one minute from St Peter's Square.
The Castel Sant'Angelo is four minutes away, and you get stunning views of the castel and the Vatican from the bridge.
I stayed one month- if you have to work, the WiFi is excellent- and was able to walk absolutely everywhere (bring good shoes). It's 15 minutes to Piazza Navona, 20 minutes to Piazza del Popolo, 10 minutes to the Vatican Museum, and it's a beautiful 20 minute walk along the river to Trastevere.
I was here in November and the weather was great, which meant everyone was eating outside, so if you get annoyed by people having a lovely time whilst eating the world's most delicious food right underneath your window, maybe choose somewhere less central.
I'm jealous of everyone who books this. I had the best time.
