Illya is a wonderfully friendly and helpful host, and gave some fantastic suggestions for things to see and try in Florence. The place is quite well located, only a little north of the main city centre, and the main attractions are an easy 20-30min walk away.
Check in was fluid and the room was set up very nicely. The only small issue I had was that the bedroom door doesn't really close, but there is a chain lock installed to keep it fairly shut.
Overall, for the price and friendly hosting I would highly recommend Illya's place for a stay in Florence.
