I let Gianluca down. I didn't throw a coin in the Trevi Fountain. Gianluca didn't let us down at all. A great host. The apartment is so well located, less than 10 minutes walk, even with a bad leg, from the Vatican and well positioned for the rest of the city. The neighborhood is safe and quiet, and Gianluca had negotiated some nice little deals for us with local bars, cafes and restaurants. I didn't need to trouble him too much, but I think nothing would have been too much trouble for him. Many thanks Gianluca.
