Contrary to what a lot of the older reviews say, I found the flat ideal for a short stay in Florence. It has everything you could need while there, including cooking stove, things for ironing and even a washing machine. The reviews that said there's no WiFi are outdated; I had WiFi and it worked perfectly. Also, I'm not sure why people moaned about the flat being a bit dark, that's true but I don't think people go there to spend the entire day in the flat, so I hardly think that's a fair criticism.
Lastly, I'd like to thank Aigul (who met me when checking in) for her friendly and hospitable attitude. Highly recommended!
