You should book Lucia's apartment for three reasons:
1. Location. The location is perfect. You can see the Pantheon right outside the window and it's a great, central spot for sightseeing.
2. The apartment itself is wonderful. It was clean, spacious and just what we needed. We enjoyed hearing musicians play (but not too loud) in the piazza from the living room but the bedroom was nice and quiet. The bed was comfortable and Lucia provided a nice baby crib for our daughter. The bathroom was nice and spacious, which is often hard to find in Europe.
3. Lucia is a top-notch host. She was extremely friendly and available whenever we needed her. We had an unexpected health emergency during our stay and Lucia went out of her way to provide us with help and support.
We hope to return to Rome soon and will definitely stay at Lucia's apartment!
