We enjoyed our stay at Alessandro & Azadeh's apartment which is a stone drop from the Duomo. Our host explained all functionality and nearby attractions very well, was helpful when we had specific requests, including booking us a taxi. The apartment was neat and tidy, not very big but has all you need. A good security system and well-functioning A/C and washing machine. The ventilation of the bathroom can be slightly better but acceptable. Thanks Azadeh! We definitely recommend the apartment to our friends.
