Ada's place is wonderful. The apartment is bigger than we thought, very comfortable, nicely decorated with many touches throughout that help you feel at home. The kitchen is great with everything you need to cook if you so desire, and the bathroom and shower are excellent, modern, and work without a problem. There are 2 big windows and a huge glass door to ceiling door that opens to a small balcony that leads to the terrace. The view from the huge terrace is a spectacular 360-degree view of the nearby Duomo, Palazzo Vecchio, etc, and the hills in the distance. As you see in the photos, but even better in person.
The location couldn't be better for us, we loved the area and it is an easy walk to many areas of interest. A few steps away from Piazza Della Santissima Annunziata and Piazza San Marco on one end and Santa Maria del Fiore on the other. Also, very easy to find.
As for the stairs, yes, as mentioned in many reviews and in the description it is on the 5Th floor, but they are wide. A fit person can go up in one go without a problem, and if you are not that fit you just go 2 or 3 flights and rest for a few seconds and you will be there in no time. No big issue and the apartment, view, terrace, and location make it worth it.
Ada is an amazing host, A +! A very nice person, fast communication at check-in and out, and if you have any questions she answers right away. We were very pleased with our stay at Ada's place and truly recommend it!
