Our stay at Elena's apartment was wonderful. As noted in other reviews, the walkup is not for the faint of heart. It's a lot of stairs. Especially hard if you have luggage. But the view is worth it. I stayed in the master bedroom and I almost felt like I could reach out and touch the Duomo from my window. You can also see the same view from one of the other bedrooms and the bathrooms. The terrace view on the other side is quite nice as well. The place was clean, all the outlets except one worked, great layout, very cozy/homey vibe. Literally 2 minutes walk to the Duomo. The shower pressure wasn't great but that just seems to be a problem in Italy in general.
Overall, really great stay. Grazie, Elena!
