We really loved Nicola's apartment, small and cosy, perfect for two people. We found it very clean and it had anything we needed. The flat is very well located close to an A-Line station so you can get quickly to the city center and Vatican. The balcony was great but unfortunately we couldn't enjoy it much due to the cold weather.
Amazing local tips, we tried some of them, Good Good pizza place was just the best.
We definitely recommend Nicola's apartment to future guests ( especially if you wish to feel like a local after long days in the touristic areas) :)
