I stayed at Ricardo's for a month. The location is easily accessible to all the central attractions on foot. I averaged 10 km a day on foot and could stop in to the apartment throughout the day, if necessary. Out my bedroom window, I could see people walking around the cupola of The Duomo, 50 mtrs away was Palazzo Vecchio, amazing location. Yet, as it's on a tiny and not heavily travelled street, I didn't feel like a tourist until I hit the squares.
The apartment is on 2 levels, 2 flights up and no elevator. It's a welcoming, traditional apartment with high ceilings. It's sparsely furnished, If you're a cook, you'll want to buy your own herbs, spices, oils etc as nothing is provided. There was tea and a bit of coffee. I replenished it. The bed was very comfortable and the bathroom worked well.
The night I arrived, I met Ricardo at 9:30 pm, all was well, he showed me how to heat the water and the apartment. Unfortunately, after he left, it didn't get warm, that's the night the heater decided to brake. I didn't want to call after midnight. I went to a cold bed with the remnants of a peel off mud mask on my face and moisturizing goop on my hair.. I was quite a sight. It's all laughable now. Ricardo's brother, came right away the next day to take a look. Brought a pro in to fix the heater and all was well for the rest of the stay.
I found them easy to communicate with. I'd happily stay again. I might ask for more towels then just one set though. That's it. Lovely place and great location.
