The only "problem" I see is the overcrowding of the (beautiful) Campo de' fiori. Market and tourists in the morning, tourists in the afternoon and drunk tourists in the evening/night. Other than that, it's centrally located, you can reach almost everything worth seeing in a few minutes (exceptions: Vatican and Colosseo, both about 15-20 minutes away). As for the weather, don't worry. Although it may rain somewhat more often in February, within the first 10 seconds after the first drops fall down, all vu comprar in the city selling tourist cr.p or handbags switch to selling umbrellas. I've alway wondered about the logistics of this operation but that should go into a new thread.
