Valter was a great host. Accurate and responsive. He also took 20 min to introduce me to the city and gave me many tips and tricks which made me feel immediately like I knew somwhat the city.
The apartment is truly ideally located. 10 min walk from the train station, 2-10 min from anything else you want to see in Florence. Nice and comfortable place for two people. Despite being very central we found the place very quiet. Oh and I love the high ceilings.
