I stayed at Dianele & Clara for almost two weeks and really enjoyed my stay.
The place is really well located, very nice coffee shops & restaurants around. We could walk everywhere within 15 minutes.
They were on place everyday to do the cleaning, this apartment is the cleanest I ever seen on Airbnb. Whenever I had a question, they would respond in an hour.
I recomand this place for your stay in Firenze !
