Stayed with my wife 5 nights at Mikes place as part of our trip to Italy.
Our host Cosimo was the best, very informative always ready to help. When had trouble with wifi, came by within the hour to assist, booked us taxis and gave great recommendations for tours and places to eat.

The apartment itself is perfect for a couple to explore Florence. Located in the historic city center, close by to the Arno river, tourist attractions, museums and shopping.
It was super-clean, had everything you might need (iron, fridge, air-conditioning, wifi etc).

Would come back again if ever in Florence.
