Eugenia's apartment is great....much larger than the pictures portray. Bathrooms are good especially coming the States. Lots of pressure and warm water. Bedeooms are big as well with very comfortable and firm beds.
The location is unreal. Walking distance to Piazza di Spagna (1 min) and other major sites of the city.
Be advised that it's extremely noisy at night - only was a problem when I had to wake up for an early morning Vatican tour. The other nights, we got back after the restaurants closed down.
I am coming back next year and will definitely rent an apartment from Eugenia again.
Side note - Eugenia and her property manager, Daniele, are very responsive!
