There is plenty of accommodation within walking distance of Bellevue Syrene. There is not one hotel specifically we are recommending.
When we visited for our tour, we stayed at Hotel Michelangelo - about a 10 minute walk from the hotel, and 5 minutes from the train/bus station. There are multiple 4 star hotels in the area immediately surrounding the venue, but are too small to accommodate a block for us.
Parking is very limited, and we need to inform the venue how many cars we estimate. If you plan to drive, please let us know ASAP

We purchased our October 29 flights on June 29 last year, at the advice of our flight alert. We paid $300 per person round trip to Rome
