This flat is very nicely done, and huuuuuuge! There were three of us over four days and we had plenty of space. The neighbourhood is lively, there are numerous places to eat and go for a drink.
It's a good 20 minute walk to termini, but it's convenient to have both metro lines there.
If you're a light sleeper, pack some earplugs! The walls are very thin, you can almost have a conversation with the neighbours upstairs.
Anthony was very helpful and very responsive. Giacomo, Anthony's friend, met us at the flat to give us the keys. He was also very helpful. Anthony was flexible and let us leave our suitcases at the flat before heading back to the airport. We were also able to check-in a bit earlier which was very convenient.
