This might be our favorite apartment we've ever stayed at in Italy over our six trips. The location is outstanding. It's a beautiful apartment. It has air conditioning if you need it but it has windows that open to opposite sides of the building, meaning you get a wonderful cross breeze if you want it. (It's on the top floor (Italian 5th, US 6th floor) with a traditional elevator.)
The street noise was surprisingly low, considering it's an active neighborhood, and the soundproof windows handled it beautifully. The washing machine (which is tinier than American machines, but not a problem) came in really handy, as did the drying rack that you can set up.
The bed is extremely comfortable and there are extra pillows, blankets, and a down comforter, if you want/need them. The shower is just a little small by American standards, but pretty generous for Italian standards and much bigger than some that we've seen.
You can tell from the photos that it's a beautiful apartment, but what you can't tell is that Silvana is an excellent host, dedicated to making sure her guests have whatever they need. (Her husband is also quite charming, but doesn't speak English.) This apartment has been in her family for decades and she's clearly proud of it, as you can see by how well it's appointed. I really can't say enough good things about this place. Absolutely loved it.
