Francesco's place was beautiful. It was a very stylish apartment with more than enough space for 4 people. His wife ludovica came to give us the keys and explained everything in the apartment. She was so pleasant! She spent around half an hour with us and gave us tips on all the best local places to eat at.
They apartment is around 10 minutes walk from the metro line and 15 minute walk from the vatican. So its location was quite convenient. I would defenitely suggest this place if you are staying in rome!
