Family of 5, including kids 5, 11, and 12 - and it was perfect. My youngest ADORED the chandeliers. We stayed 10 days and we would stay again! Just close enough to busy things (close to Piazza di Spagna, also felt like a 20-minute walk to most of the really awesome parts of the city), but far enough away that there wasn't incessant noise. Note on public transport: lots of buses and trains. You can buy bus or metro tickets at the metro station or at some tobacco, convenience stores, or supermarkets around the city - but you have to pay cash at stores. In the metro station there are three ways to purchase - you can go to a person in a booth and pay cash or card for a one-trip pass or 1, 2, or 3-day pass. You can go to a kiosk and pay cash for individual tickets that last for 100 minutes so you can transfer to other trains or buses as part of your trip. And you can use your credit card at the gate - one credit card for one person, you can't use it for multiple people and it doesn't transfer. Kids under 6 are free so just shuffle them in with you at the gate. There was a lot to do, both tourist things and also with good wifi in the house (multiple devices streaming usually worked) and the pool/tennis table, which the kids also really enjoyed...because kids can only handle so much touring. Kids loved their own beds, and we even had one kid that rage quit the kids' bedroom and was able to crash on the couch bed in the living room the rest of the time --- which was fine with us. Plenty of hot water, a washing machine in the kitchen, and windows that open wide to the glorious Italian weather. Well-equipped kitchen is critical for a big family and this one had a small sink but an oven and cooktop as well. The Coop is the best-priced and equipped supermarket, steps away, and you can get excellent food everywhere and great, inexpensive wine, too. Federico was incredibly responsive and helpful - if there was anything we needed he was able to help within a very short time, and as people who are traveling frequently, there is a ton of value in that kind of reaction.
