Nicola, his housemate Andrea and dog Spina are very nice! Very easy to get along with. On our first day, Nicola drove is to Piazzale Michelangelo, the first in my itinerary list. He even offered to meet us at night to drive home together and bring us to "the mall" too. He is very thoughtful, he isn't just there to host you, but he will try to make your stay enjoyable.
The apartment is in a nice, quiet and safe area just outside the very busy city center. You can take bus 6 which five minutes walk from the apartment and it will bring you to the Firenze SMN (15mins) and the Duomo area (20 mins) and even to the other side of the river. Florence bus timing are quite accurate, you can plan your time and not waste it at the bus stop.
The room is spacious and clean but be prepared to welcome Spina (the dog) in your room as he sometimes try to sneak in. :) The toilets are clean too.
Had a wonderful stay in Florence, now one of my favorite cities. Thanks for hosting us Nicola and for teaching me how to use the Bialetti. Hope to see you in Singapore soon. Ciao!
