Lucia's place looks exactly as it does in pictures. It's around 3 blocks away from Ottaviano station / around 10 minutes walk to the Vatican. The neighborhood is safe and well-lit at night. There are 2 convenience stores, and a few small cafes nearby, but there are drinks in a small fridge for sale - the bottled water costs the same as in the mini stores downstairs.
The room is bright, modern and clean. The bed comfortable. The bathroom is different from the one presented in this ad but it looked just as nice and modern. I slept well on both nights :)
Breakfast was served around 8 (or 8:30?) and there was a lot of food to choose from. Oh yes, Rocco, Lucia's boyfriend, was at the reception when I checked in, and he allowed me to have breakfast while I waited for my room. (So nice!)
Highly recommended. Good value for money. Will stay there again.
