I can absolutely recommend this accommodation! The room is clean, cosy and goes to a quiet courtyard. It is very close to the main station and in walking distance to the main sights (Duomo, Ponte Vecchio, Uffizi). There are good and affordable restaurants nearby.
The room is very nicely designed and have everything you need: towels, WiFi, a small fridge, water boiler, hairdryer, AC, TV (didn't use it though) and some nice little extras (sustainable (!) shampoo, conditioner and body wash, small bottle of water, instant tea and coffee). In case you wonder - yes you can drink the tap water in Florence.
The hosts were very friendly, replied immediately and could help with every request (e.g., depositing luggage after check-out).
Thanks for everything and I hope I'll be able to come again!
