Gianni is just the best host you could wish for in Rome. He is really helpful and well organized in case of any questions.
The accomodation is also just perfect, clean and has everything you need for a vacation in Rome (even a wine bottle cooler for example). Though it can be a bit loud, since the main street is right outside the bedroom window. It is 30 min. by foot to the Colosseum and 20-25 minutes to the lovely quarter Trastevere. We had a wonderful time in Rome and beautiful Tiberhaus! :)
