Anna's place was great. It was very convenient, as it is away from the crowds, so you can sleep at night, but close enough to walk to all of my tours within 15 minutes. I am a fast walker, but maybe we will say 20 minutes for the average person.
The room was very clean and organized. The mattress was firm, but comfortable each night. I had to learn how to use the shutters, but that wasn't very hard to figure out.
The bathroom is small, but functional, and extremely clean. The shower is especially small, maybe 3'x3' (1 sq meter). I would say that if your BMI is under 30, you would be okay.
The wifi is okay in the room, but at the far corner, where the table is, it gets a little weak for cell phones. My computer did just fine though.
I think my biggest concern was getting bitten by mosquitos at night. The first 2 nights, I suffered through it, but I couldn't deal on the third night. I ended up using the fan in the closet and having it constantly blow over my head (no oscillation), so that the mosquitos couldn't land. Super effective.
The thing I loved the most was the pamphlet that she put together that contained a little history with maps, Italian phrases, essentials for everyday living (like watching out for the carts, or high tide and flood warnings), and recommendations for food based on location (which of the six areas), type (bacaro, restaurant, bar), and what food they are good at or known for.
