We didn't meet Luca personally but he was very responsive and a great host. We ended up staying in a different apartment since the AC in Guicciardini suit broke down couple days before arrival. However Luca was very accommodating and moved us to a different apartment that was in even better location and right in the center of Florence. We greatly enjoyed the place it was very clean and lovely decorated. The location was truly amazing since we could get to all the attractions that we wanted to see within few minutes. Luca's colleague that checked us in was very nice and waited for us under the apparent and even helped with the luggage. He also gave as great recommendations for restaurants and ice cream places. Highly recommend the Santo Apostoli luxury apartment that we ended up staying in. We had a lovely stays in Florence.
