Everything was was perfectly fine. The appartment is near the main train station and directly near the tram. The host has placed a paper with number of taxi in the appartment so it is easy to explore the city of Florence.
I was also surprised about all the little details which you can find in the appartment: Tea, coffee, masks, sanitizer, number for taxi, books everywhere, games, decoration,... The air-conditioner is great and helps during the hot summer time.
Donella is a great host and helps right away when you have questions and need some more info. Also check-in was super easy.
