Marina is an exquisite host who is as capable as she is elegant. She was quite prepared to greet me in English, but when I explained through my broken Italian that I wanted to practise she was compassionate and understanding. She spoke slowly, used simple words and repeated things where necessary. Truly lovely. She's also incredibly knowledgeable about the city and will give you a week's worth of places to explore if you've got the time!
The space itself exceeded all expectations. It was spacious, elegantly furnished, and generally very classy. To say it was tidy would be an understatement; I'm talking floors so clean they literally squeaked. I had to take my shoes off each time I came in just because it would be a sin to walk through and contaminate such a lovely space.
One thing to take note of is that breakfast is partly supplied by meal tickets to a local cafe. While the cafe is excellent, the staff there are perhaps not quite so patient with foreigners as Marina. Despite having visited Italy once before, traditional Italian breakfast (caffe e cornetto) was not at all what I expected, so if you're not local, I'd recommend looking up a quick guide to help you know what to expect and to make your order coherently.
Certainly an excellent arrangement for those looking for an authentic Italian experience.
I would highly recommend Marina's listing to my friends and family.
