We (me, husband, and 2 boys 8 and 10) had a great 8 night stay at Lavinia's apartment! The apartment was perfectly situated right near the Pantheon, and was a short 10-15 minute walk to most of the major sites - the Forum, Trajan's Market, Spanish Steps, etc. there were many restaurants nearby, too, and a grocery store about a 10 minute walk away.
Lavinia was a great hostess - she met us the first morning we arrived and explained everything thoroughly. She was also in touch if we needed her, but not intrusive. There was also binder in the apt. with information on restaurants, maps, wifi, etc. The apartment itself was also great - 2 big bedrooms, 2 bathrooms, a large sitting area, kitchen with all the necessities for cooking and a washer/dryer. The a/c in all the rooms was also great for the hot afternoons. The beds were comfortable and having 2 bathrooms for 4 people was also really nice. All very clean and modern.
The restaurants outside the apartment stay open until midnight and you could hear some noise outside with the windows closed, but we brought a white noise machine for our kids' room and my husband and I just stayed up. After that, it was very quiet. It wasn't an issue for us at all.
All in all, it was a great place to stay and I would go back in a heartbeat. Thank you, Lavinia, for being such a good hostess! We really enjoyed our stay in Rome.
