Amazing place - we would highly recommend for people coming to Florence! We were three women (mother and two daughters) so the accomodation was perfect for us as there is only one bathroom with a shower that is part of the main bedroom so we did not have any issues walking in and out of rooms like that. I think it is better suited to a family like that, as opposed to two couples as you do have to share spaces. It was so big and we loved we could spread out. Being on the other side of the Arno was great too as we could experience the shops / restaurants that the locals went to. There is a corner shop close by for your essentials. But please note for people with young children, heavy baggage or mobility issues: there are approx 60 stairs to go to the apartment entrance. Once you're in, the way to the bedrooms is also using more stairs. The mezzanine stairs can be a little steep so I would not recommend them for young kids. We also struggled getting the gas hob to work at times but that was likely user error and we did not need to use it too much. It was nice having a kitchen with a kettle, fridge and toaster for some breakfast. I would also note that the milk in italy is different to the uk stuff so maybe bring a small amount of your own for tea.
Overall a great place and we would recommend!
