We've stayed for 3 nights in August at this very nice and cozy apartment. It's centrally located, which was perfect for exploring the city (about 15 min walk to Palazzo Vecchio or the Dome) and is also very convenient for exploring the southern part of the city. At the same time it's located on a quite street. The apartment itself is stylishly decorated and very well equipped, the bedroom is very spacious and comfy, with high ceilings, the bed is very comfortable too, we slept very well. The two installed silent air conditioners also made the stay comfortable on hot summer days. Also it was spotlessly clean.
We didn't meet Elisabetta and Leonardo, but if we needed something, they were always there on chat and very fast to respond, so the communication was very good. It's great value for money. The only thing is that it doesn't have a lift, which wasn't a problem for us, but may not be suitable for everyone. Our full recommendation on this one 👍
