This place is just remarkable. Spotlessly clean, and you could have a magical visit and never get in a vehicle of any kind.
We are a family of 4. The children are 15 and 13 - boy and girl. They each got their own bedroom - that alone would make it worth it. It's more than spacious enough and the furnishings are of very high quality. My son has recently had knee surgery so the lift was a big help. The kitchen is very well equipped and there is plenty of natural light. All the bedrooms are big with lots of storage. It was easy to keep it uncluttered. The bathroom is surprisingly big and hot water was never ending.
But as terrific as the apartment is, the location is the key attraction. Every morning we'd walk directly across the street for a cappuccino and cornetto. Then there isn't a single important part of Rome you can't walk to. We even walked back from a magical bike ride on Via Appia Antica to the apartment by way of the Colosseum. It was not a long walk. Maybe 45 minutes?
And there is a wine store/bar that is again, 20 meters from the front door. Actually, you have to have a glass of wine, stand on the steps of the store and enjoy a Roman night with the locals at least one night.
There is nothing, nothing that you can't find within 200 meters. Pharmacy, cleaners, food shops, incredible restaurants, a fun bar (Captain Cosmo), jewelry maker, art galleries (many), Segway rental, scooter rental, and a farmer's market outside your door on Sundays.
We spent six nights. I don't like to go anywhere twice but we'll be back to Rome. And there is absolutely no reason to stay anywhere else.
Luigi was great, always available and he's found a great limo service from the airport. Mr Luis and company are pro's. You are a 10 minute walk from: piazza's Navonne, St Peters, the Pantheon, St. Eustache (oh God, the coffee...), Campo de Fiori, the Tiber, Castle St Angelo, many dozens of restaurants, many dozens of galleries, museums (we saw a wonderful Escher exhibit). Whatever you do, get lost. Just wander and enjoy and be grateful you aren't going back to a hotel.
