About hotels in Rome, I stay there last year in the Hotel delle Muse, Via Tommaso Salvini 18, Roma (Parioli) http://www.hoteldellemuse.com The head of the hotel is Giorgio, a very nice man, and the hotel is realy well on price. The only problem is that is a little far from the center, but you have a bus that takes you directly to Piazza Venezia, that makes the hotel very interesting. The breakfast is wonderful, and the restaurant is also very good,

If possible ask the room 21, is the best of the hotel, with very nice views to a private garden...

Hope this will help you. Regards, Asier
