Valentina is great. We received such a warm reception, it was as if it was old friend seeing me again. The place was great and the coffee and biscuits were nice to start the day or to take a pause with during a long day. I had good luck finding free parking when we got there but I can see how that may become hard to find. Super close to Vatican City, Trastevere will be about 20 - 30 min walk. Used this location specifically for the Vatican City so can’t really comment for the other sights in Rome. Will look for this place again for our next Vatican City visit.
