What can I say about Catia and her apartment aside from simply amazing. She deserves to be a super-host and it shows why. From the time of booking through our whole trip, Catia was in touch the whole time and so helpful.
We took a Taxi from the train station, about 15 minutes, and Catia met us at the apartment when we arrived and had some wine and a beer and some local candies for us, it was such a sweet touch. There is an elevator in this apartment which makes it easy. Catia went over everything in the apartment and was able to show us where all the sights were, both nearby and throughout Rome as well as recommendations for dinner etc. The apartment itself is gorgeous with great little touches. Plenty of room for the 3 of us when we stayed in June 2019. My daughter had a whole room and bathroom to herself and the same for my wife and I. Everything you need is available; towels, shampoo, soap, all kitchen utensils, AC, coffee maker + coffee, hair dryer, Iron, wi-fi and so on. There is a lovely little outdoor balcony to sit and have coffee in the morning. Right down the block from the apartment is a little bakery that serves fresh pastries to have with your coffee.
As for the location; superb. The apartment is down the block from Vatican City (10-15 min walk ). When you walk out the front door you see St. Peter's Basilica. It is a beautiful site to see each morning when leaving and each evening when returning. Other sites around Rome are easily accessible by local transportation (metro, bus) right nearby. We just used the IT Taxi app and were picked up right at the apartment. We had no issues and made it easier and quicker to get around we felt. Catia is also a licensed guide so she can help book any trips or tours you may want to do.
All in all there is not one bad thing I can say. It was a pleasure to get to meet Catia and see how much she loves 'her' city and how knowledgeable she is. We would absolutely look to stay here again when we come back to Rome.
