Luca is a great host! He replies back all the messages pretty quick and answers all my questions and doubts. He is easy to cooperate with.
For the apartment, i must say it is beyond impressive. I travelled with my family, and it is still spacious even for 5 of us. It has 2 bedrooms and 2 sofabeds. It doesn't have too much furnitures so it feels roomy. The apartment and furniture was new, clean, classy, and has all the things you need to stay. The internet is fast. Not forgetting the location which is in the most strategic place in Florence. It is walking distance to the station and all the places you want to visit in Florence, also to supermarket and restaurants. And still you can sleep tight without hearing the noise from the crowd on the street.
I must say the apartment is totally worth the stay. Even my parents (who are hard to be satisfied) would love to stay there again.
