It's been lovely to stay at Cristina's.
The apartment is big and quiet and the metro is just few steps away, even walking down to the Vatican area is a nice stroll in a sunny day.
We rented bikes for the entire stay which makes the visit of Rome much easier. We had a few issues on the first day to find a way to store them but the the concierge let us put the bikes in the basement.
Internet at Cristina remains iffy, it works sometimes and then it stops.... But after the fiirst couple of days it was not a problem anymore as we knew and got organized.
The owner welcomed us and had prepared some grocery for breakfast. Thanks!
