This is an amazingly vibrant apartment in a really central location. It's quirky in an authentic kind of way. Awesome bathrooms too! Martina Laura was wonderful - interesting and engaging, and incredibly helpful!
Note - as the description says, there are stairs - 61 of them. They aren't difficult to climb, but I don't think there's a lift. Having said that, the climb is well worth it (and the peculiarity of the parallegrammed staircase is another quaint oddity of this place).
The marketplace is noisy at night. The apartment has double-glazed windows, with shutters, so the noise and light can be blocked out. It's a busy, bustling place so if you want silence book somewhere out in the country. Better still, immerse yourself in what the mercato and surrounds have to offer!
This place oozes history. If only the walls could talk (more than they already do!).
