I spent eight nights with my wife, sister, and brother-in-law at Maria's place. She met us at the flat and gave us the key and a look around the place. Although she doesn't speak English, we were able to communicate just fine with Google translate and motions. Maria gave us a very warm welcome--just like going to visit family. She had wine waiting for us, and croissants as well.
We used public transportation a lot, so the 10-minute walk to the train was quite convenient. It's close to the sea and to old town; you can be at the sea in two minutes and in old town in just over five.
The flat is quite spacious and nicely furnished, making it comfortable to spend time in. We found all the necessary utensils in the kitchen to cook a couple of meals. The living room/dining room is quite spacious and a comfortable place to relax. The only potential downside is some noise from the neighbors when you're in the main bedroom. We didn't hear loud noises, but you could hear footsteps, the radio, etc. I slept just fine but a lighter sleeper might be bothered by it, especially if you're not on Italian time (up at 7, afternoon siesta, up until midnight or later).
All in all, Maria's flat suited our needs perfectly and she was the best host a person could hope for.
