One word best summarizes: sumptuous! We stayed here towards the end of our 2-1/2 week trip in Europe and, to be honest, stretched our budget to splurge for a great place. We were blown away! The photos in the ad don't do it justice -- and frankly I'm not sure any photos would. You need to be there to experience it. There was only 1 review available before we booked, so I'll leave a bit longer review here.
Irina greeted us on arrival, was gracious and very helpful with tips getting around Florence and recommendations to eat. She checked in with us part way through as well to make sure things were going well. The unit has been heavily designed and decorated but done very tastefully and in a way that is a great experience. It feels like you're living in a Renaissance/Baroque palace or maybe some version of Versailles! It was fun to be there and just look at the apartment, explore, and appreciate the furniture and decor. Even more so, we appreciated that everything that we needed, and more, was available (like slippers, extra tissue, kitchen utensils and supplies, a couple bottles of water). Having laundry was really helpful during our stay. There's a small, European-style elevator in the building that avoids any stairs, so the only mobility limitations around there would be the cobblestones and curbs outside. You can't get a cab from there directly, but there are a few hanging around about 1-2 min walk away. The location is adjacent to the Duomo, and a short walk to the other tourist attractions. There are cafes, gelaterias, and restaurants next-door, and a few grocery stands and markets within 1-2 blocks walk. The building itself is very quiet, and I don't think we even saw any other tenants. When the weather is nice it was good to have the windows open, but there is noise (chatter, music from street performers) that comes up. The soundproofing windows blocks out ~90% of the sound so it's not much of a bother. During the night it was very quiet in the neighborhood. There are A/C units in the main room and bedroom, which was helpful for the hot days.
All told, a great place to stay in Florence if you're looking for a special and extra interesting experience! Highly recommended!
