There is no official hotel for Mambo Italiano as the venue is not a hotel. However there are many accommodation options around the area as it is very central (10 minutes walk to the central station and 10 minutes walk to the Colosseum).
Here is a screenshot from Booking.com with the price for Friday-Monday (prices may change) and the venues of Friday and Saturday/Sunday marked in red arrow.
We also recommend Airbnb where you can find cheaper accommodation options to share.
