The place is well located, close to many museums and churches. It's about 30 mns walking from Santa Maria Novella train station, which was a bit of a challenge pulling suitcases on cobbled streets in a hot summer afternoon. For our departure, Jonny kindly helped us to book a Taxi to return to the train station.
To reach the apartment you need to climb through steep narrow stairs. It was ok with our carry-on luggage, but might be a problem with heavy luggage. There's a super market almost next door. The apartment is well ventilated and also has AC in the main bedroom and kitchen/dinning room.
