We had a lovely stay at Ekaterina's place. Valentina warmly welcomed us after a long flight from the US and helped us get situated and comfortable. The apartment is in a gorgeous old building on a gorgeous old block. It was stylish, bright, and pristine. We loved the retro wall paper and grey floors. It's in a fabulous and central location (wonderful restaurants, sites, etc.)--but more chill than the epicenter of historic/touristic center. Our second night was a little loud b/c of the bars/restaurants on the street--but it wasn't a big deal. We'd heartily suggest this as a great place to stay in Rome!
