It's hard to overstate how amazing Fidia's place is, especially for larger groups of friends visiting Rome. It has palatial ceilings, is beautifully furnished and air conditioned, and has a wonderful vantage point over Piazza del Popolo.
For groups like ours that worry about our noise level affecting neighbors, it is isolated from other residences-- a huge perk. Fidia is also an excellent host who clearly communicates the rules of the property and responds quickly to requests for support. If you are looking for an ideal group stay in Rome, look no further!
