The house is about 10-12minutes walk from St. Pietro bus station NOT St. Pietro church. St. Pietro station is the last station for number 64 bus.
St. Pietro church is about 15-20minutes walk from the house. My daughter and I walked to visit Vatican. The house is nice, Gaia’s easy to communicate and she will load you up with very valuable information. How to skip the line in order to visit Vatican and other info. We glad to stay in her house. Thank you,
