This house has a little rare layout which I couldn't tell from the pictures. It was clean, in good location, and a big extra point is that they have a bathtub! It was working perfectly.
However, bedroom was dark, only has lights for the mezzanine and small bed light. And so was the bathroom. Right side of the bathroom was very dark, we had to use toilet in the darkness.
Communication with the host was ok, they responded us quick. However, during 5 days of stay they contacted me if they can come to the house to do some technology improvements (I don't really know) which we didn't feel comfortable. They asked me what time we would check out for three times during the stay so I had to respond the same answer again and again, and they contacted me on the very last day of our stay, right before our last dinner, insisting that they have to check the house before we check-out (which I had never experienced). So we had to squeeze in their request on the very last night.
So it was little tiring for me to communicate with them.
Overall, it was a OK stay. Clean house with amazing location, and you can take a bath which is rare in Florence. Last thing, make sure you know they would charge extra money in cash if you check in after 9pm.
